List of Scooby-Doo! Mystery Incorporated episodes

This is a list of episodes for the animated television series Scooby-Doo! Mystery Incorporated, the eleventh incarnation of Hanna-Barbera's Scooby-Doo series of Saturday morning cartoons. The series is produced by Warner Bros. Animation. Unlike any previous series, Scooby-Doo! Mystery Incorporated features an overarching story. In addition to the traditional cases they always solve, the team finds itself being nudged into the uncovering of a dark secret that is hidden in the past of Crystal Cove, covered up by parties unknown. Following cryptic hints from a faceless mystery-man known only as "Mr. E" (a play on "mystery"), they find themselves caught up in the unsolved, decades-old case of the disappearance of four mystery-solving youths and their pet — the original Mystery Incorporated.

Once again Mr. E intervenes to help the gang solve the mystery. Villain: Humungonauts/Max and Jax Minner Note: This episode is an homage to the movie The War of the Gargantuas, going so far as to reference the song "Stuck in My Throat" performed by Fran Southworth, written by H. B. Barnum and produced by Joey Levine. The Don-Knotts-lookalike can be seen sitting at a table in the cold open sequence. The Sheriff hypothesizes that one of the Humungonaut's green fur is the result of "outer-space gamma rays", a reference to the Incredible Hulk.

The auctioneer appears to be based on British TV antiques expert David Dickinson. There are a few similarities between this episode and the Scooby-Doo and Scrappy-Doo episode "I Left My Neck in San Francisco". Both episodes feature a female vampire as the monster of the week. Both episodes also use members of the Blake family as prime suspects for the person behind the disguise, although in the former, Daphne herself was the suspected culprit, not her mother.

After catching Char Gar Gothakon, the gang reunites only to find that Mr. E has left them a box belonging to the Darrow family, along with a note which reads that the old Mystery Incorporated might never have disappeared if they had this box in their possession. Upon opening the box, its contents are revealed to be an entire history of Crystal Cove. Velma states that it seems that one mystery has now become two. Overarching Mystery Event: Darrow Family Archives stolen from the university by Mr. E. Villain: Char Gar Gothakon/Howard E. Roberts Note: This episode parodies the "Cthulhu Mythos" of H. P. Lovecraft. Howard E. Roberts is a reference to Lovecraft's friend and fellow writer Robert E. Howard, although they have little in common apart from name and appearance. Writer Harlan Ellison voices himself, though the animated version appears as he did in the 1970s.

Villain: Aphrodite/Amanda Smythe Note: This episode parallels the book and films based on Jack Finney's Invasion of the Body Snatchers, and the moment that motivates the villain is an homage to a moment in the movie Carrie.

27	1	"The Night the Clown Cried"	Curt Geda	Mitch Watson	March 30, 2012 (Cartoon Network Video) July 30, 2012 (TV)	June 2, 2012 (UK) September 1, 2012 (Latin America) September 10, 2012 (Poland)
Following the disbandment of Mystery Incorporated, Mayor Fred Jones Sr.'s successor Mayor Janet Nettles is approached by a mysterious figure (who later turns out to be Velma). She shows the mayor files on her fellow mystery-solvers in order to seek their help in bringing down Crybaby Clown, who is terrorizing Crystal Cove. Mayor Nettles sets out immediately to retrieve Scooby-Doo and break him out of the "nice farm" that he is in. Scooby then helps Shaggy escape from military school and together they find Fred (who now has the appearance of a hobo) and the three return to Crystal Cove. Velma joins them and together they go to bring Daphne back, but she, still angry with Fred for leaving her, refuses their offer, as she has a new boyfriend now. Fred comes up with a doughnut shop-themed trap in order to trap out Crybaby Clown. The trap doesn't work and Crybaby Clown escapes using one of his bottle bombs to blow up Chen's Fireworks. Fred is depressed that the villain escaped and states that Mystery Incorporated won't be the same since Daphne is never coming back. Villain: Crybaby Clown Note: Daphne's new boyfriend, Baylor Hotner, is a parody of actor Taylor Lautner and his success in the Twilight film saga. Velma's action and a throw-away line in this episode are similar to those of Rorschach of the Watchmen comic mini-series by Alan Moore; Velma even references Rorschach by name in this episode. Crybaby Clown's speech at the town hall meeting (after he rakes his nails across a chalkboard) parodies the scene from Jaws in which the shark hunter Quint (played by Robert Shaw) makes his first appearance. Within his speech, Crybaby Clown mentions two villains from the classic Scooby-Doo, Where Are You! series: Mano Tiki Tia and Redbeard's Ghost. This episode and the following one open with no credit sequence, just the title, to underscore the disbandment of Mystery Incorporated.
28	2	"The House of the Nightmare Witch"	Victor Cook	Adam Beechen	July 31, 2012	June 3, 2012 (UK) September 8, 2012 (Latin America) September 11, 2012 (Poland)
Velma and Hot Dog Water are discovered to be working for Mr. E and are going on missions for him; here they go to Russia to retrieve a piece of the Planaspheric Disc from an old house, but when they are stopped by the guard and the nightmare witch Baba Yaga comes to life and attacks them, they buy the house and bring it to Crystal Cove, where the house springs chicken legs and rampages around town. Meanwhile, the gang is looking to replace Daphne, and Velma suggests Hot Dog Water (who is out on parole for helping to enhance the prison's security system). Overarching Mystery Event: The third piece of the Planispheric Disk. Villain: Baba Yaga/Curator Vronsky Note: This episode and the previous one open with no credit sequence, just the title, to underscore the disbandment of Mystery Incorporated.
29	3	"The Night the Clown Cried II – Tears of Doom!"	Curt Geda	Michael F. Ryan	August 1, 2012	June 4, 2012 (UK) September 12, 2012 (Poland) September 15, 2012 (Latin America)
Fred tries to get Daphne back while Crybaby Clown returns to rob Crystal Cove where he kidnaps a therapist, a hairdresser, a plastic surgeon, a publicist, and Daphne as well. The gang chase Crybaby Clown to an airport where he is about to take off with the five captives, but is stopped by Mystery Incorporated and they solve the mystery. Daphne agrees to return to the gang upon learning who Crybaby Clown is. Meanwhile, Mr. E tries to recruit Angel Dynamite back with him but she turns him down claiming she is no longer her alter ego and is just plain Cassidy Williams. Mr. E also mentions that "they" are coming for Fred. Villain: Crybaby Clown/Baylor Hotner Note: This episode and the next one feature "Hot Dog Water" instead of Daphne in the opening credits.
30	4	"Web of the Dreamweaver!"	Victor Cook	Benjamin Townsend	August 2, 2012	June 5, 2012 (UK) September 13, 2012 (Poland) September 22, 2012 (Latin America)
With Daphne back on the team, Hot Dog Water is removed as a member. Meanwhile, a creature called the Dreamweaver starts haunting people's dreams, hypnotizing them into giving up possessions nearest their hearts. In an effort to stop him, the gang teams up with Sheriff Stone, who, like those who have been attacked by the Dreamweaver, is a closeted Crypts and Creatures enthusiast, having invented the Dreamweaver in his youth. Villain: Dreamweaver/Horbert Feist Note: This is a parody of A Nightmare on Elm Street (Dreamweaver's power), Dreamscape (the fact that Dreamweaver invades people's dreams with a machine), and Labyrinth (the labyrinth in every dream sequence and Dreamweaver's crystal ball). Dreamweaver resembles both Freddy Kreuger and Jareth, as well as Dream from The Sandman and Marvel Comics' villain Nightmare. Also, the role-playing game featured in this episode, Crypts and Creatures, is a parody of Dungeons and Dragons. The jokes about Crypts and Creatures being addictive may be a reference to the anti-gaming film Mazes and Monsters. A fantasy sequence depicting a moment in a Crypts and Creatures game features characters that look like Legolas and Gimli from The Lord of the Rings films. This episode and the previous one feature "Hot Dog Water" instead of Daphne in the opening credits, even though Daphne was officially back in the gang at the beginning of this episode.
31	5	"The Hodag of Horror"	Curt Geda	Roger Eschbacher	August 3, 2012	June 6, 2012 (UK) September 14, 2012 (Poland) September 29, 2012 (Latin America)
A creature called the Hodag of Horror attacks Crystal Cove. Meanwhile, Brad Chiles and Judy Reeves (Fred's real parents) have suddenly appeared along with a dog named Nova (whom Scooby has taken a fancy to). At the end, the original Mystery Incorporated are called together by none other than Pericles who has an unknown proposition for them that involves the new Mystery Incorporated. Overarching Mystery Event: The fourth piece of the Planispheric Disk. Villain: Hodag of Horror/Roberto the Monkey (under the control of Ned Fussbuster via ringing bells) Note: This episode parodies Lady and the Tramp and the Hellraiser series. Nova's name is a reference to the mute primitive human character of the same name from the Planet of the Apes books and film series.
32	6	"Art of Darkness!"	Victor Cook	Benjamin Townsend	August 6, 2012	September 17, 2012 (Poland) September 29, 2012 (UK) October 8, 2012 (Latin America)
Crystal Cove welcomes artist Randy Warsaw, who presents his latest work in the Art Museum, entitled "Junk." However, this latest work comes to life and attacks patrons of the museum, swallowing members of Warsaw's entourage and working staff and turning them into gold statues. The gang is asked by Mayor Nettles to solve the mystery so the Art Museum can be saved, but this becomes easier said than done as the gang are employed as part of Warsaw's exhibit, leaving Daphne to work the case alone. After solving the case, the gang receives a radio broadcast from Cassidy Williams warning them of the evil that resides in Crystal Cove. Villain: "Junk"/Butch Firbanks Note: Randy Warsaw is a parody of modern artist Andy Warhol. The band "Sunday Around Noonish" is a parody of the band The Velvet Underground while Butch Firbanks and Eeko are respectively parodies of Velvet Underground members Lou Reed and Nico.
33	7	"The Gathering Gloom"	Curt Geda	Marly Halpern-Graser	August 7, 2012	September 18, 2012 (Poland) October 1, 2012 (UK) October 15, 2012 (Latin America)
A Graveyard Ghoul attacks in the middle of Mayor Nettles' Horror Movie Night, forcing the gang to investigate. However, Fred and Shaggy are smitten with three beautiful girls who have just immigrated into Crystal Cove, and Daphne has eaten some of their mother's homemade chocolate and become addicted, leaving Velma and Scooby alone to solve the mystery. Eventually, they are forced to turn to Sheriff Stone for help. Meanwhile, after reminiscing about how they met, Mr. E teams back up with Professor Pericles in search of what he calls "the Treasure". They decide that Cassidy Williams must be put out of the way – "for good." Overarching Mystery Event: It is revealed how Mr. E and Professor Pericles met each other. Villain: Graveyard Ghoul/Count Evallo von Meanskrieg
34	8	"Night on Haunted Mountain"	Doug Murphy	Roger Eschbacher	August 8, 2012	September 19, 2012 (Poland) October 2, 2012 (UK) October 22, 2012 (Latin America)
Gary and Ethan are attacked by the Dark Lilith on Mount Diabla and lose the soccer team's lucky soccer ball. As the gang begins to investigate, the monster attacks them and a band of hillbillies at their camp in nearby Scorpion Ridge. One of the hillbillies named "Ugly Jimmy" catches Daphne's eye for he is handsome and muscular unlike the rest of the tribe. Jimmy decides to help the gang solve the mystery. The gang falls into a cave and meets an amnesiac explorer calling herself "Boron" who is holding Fred's soccer ball, believing it to be her lover. She leads the gang to the Dark Lilith's hideout after the monster attacks Jimmy. The hideout turns out to be an old Spanish galleon. After solving the mystery, the gang is thanked by the hillbillies as it is shown that "Ugly Jimmy" was deformed in the fall. The gang drives off unaware they're being watched by the ghost of a conquistador which says the single word "Nibiru" before fading away. Overarching Mystery Events: The ship's manifest, bearing the journals of the conquistadors who founded Crystal Cove, which describe their discovery of the treasure (a crystal sarcophagus filled with black pearls) that became the evil beneath Crystal Cove (which they named for the sarcophagus) and their use of the Planispheric Disk to mark its location after its burial; the fifth piece of the Disk. Villain: Dark Lilith/"Hot Dog Water" Note: This episode is a parody of A Night on Bald Mountain. The soccer ball with a face is very similar to Wilson from the movie Cast Away. The look of the hillbillies is also based on the look of the mutant family from The Hills Have Eyes and its sequels and remakes. This episode marks the second appearance of "Hot Dog Water" as the villain, the first being in "Menace of the Manticore".
35	9	"Grim Judgment"	Curt Geda	Mark Banker	August 9, 2012	September 20, 2012 (Poland) October 3, 2012 (UK) October 29, 2012 (Latin America)
A ghostly Puritan judge named Hebediah Grim begins terrorizing Crystal Cove and judging its female citizens, forcing Mystery Incorporated to investigate. At first they turn to Gary and Ethan, but both claim to have fought the monster themselves. Ethan suggests Doogle McGuinness, but the monster attacks as the gang is investigating him. Grim then turns his judgment upon Daphne, but Brad Chiles and Judy Reeves offer to help Fred protect her, and they set up a trap to capture Grim. They encourage Fred that he will be a great "trapsman" claiming it is "in his blood" and to believe in himself as they do. It is also shown that Daphne still has strong feelings for Fred, as well as that there are feelings between Mayor Nettles and Sheriff Stone. The episode ends with Cassidy Williams spying on the gang, Brad, and Judy. Villain: Hebediah Grim/Gary and Ethan Note: This episode is a parody of the slasher genre. The costume Scooby wears while he and Shaggy are spying on Ethan at the soccer field is similar to that of Ariel from Disney's The Little Mermaid (1989).
36	10	"Night Terrors"	Victor Cook	Michael F. Ryan	August 10, 2012	September 21, 2012 (Poland) October 4, 2012 (UK) November 3, 2012 (Latin America)
A family vacationing in the Burlington Library is attacked by a shadowy fiend wearing a head similar to that of Anubis and is scared off when it assumes a werewolf-like form. Later, a landslide forces the gang to abandon their ski vacation and detours them to the same library, where they are greeted by its caretaker Dan Fluunk who explains to the gang the history behind the mansion, including that its builder and namesake had a fascination with groups of four people and an animal. Soon, strange things begin happening to the gang as their stay in the mansion progresses. Eventually, their experiences are revealed to be hallucinations brought on by the burning of a special kind of wood called Terror Wood. Meanwhile, Cassidy Williams continues her search for the truth behind what is happening to the gang now and what has happened to other mystery-solving groups in the past — including the Darrow family. Overarching Mystery Events: The repeating pattern of mystery-solving groups, including the Darrow family and both incarnations of Mystery Incorporated, being haunted by the Planispheric Disk and the treasure it leads to, all of them consisting of four sleuths and an animal mascot; the Planispheric Disk user manual. Villain: Fiend/Dan Fluunk Notes: This episode bears similarities to the film The Shining. The gang's snow suits are similar to the ones they wore in the Scooby-Doo, Where Are You! episode "That's Snow Ghost". Also, the family vacationing is the exact same family who were vacationing in the episode "The Creeping Creatures".
37	11	"The Midnight Zone"	Curt Geda	Mark Banker	August 13, 2012	September 24, 2012 (Poland) October 5, 2012 (UK) November 10, 2012 (Latin America)
A robot disguised as a Nazi World War II soldier attacks Cassidy Williams at her radio station, eventually self-destructing as Cassidy fights back, taking the entire building with it. She explains to the gang that these robots have been attacking her for the past week. Robots continue to attack the gang as they investigate. When the gang realizes that the robots are coming from deep underwater, Daphne recruits two of her babysitting charges, Tom and Tub, and their seal (also named Scooby), to transport the gang in their submarine to the robots' spawning vats, in an area the kids call "The Midnight Zone". Shortly after submerging, the sub is attacked by a group of robots and damaged, and the gang stumble upon an underwater base and attempt to use it to repair the sub, only to discover that the base is the factory where the robots are constructed, run by Professor Pericles. In the end, Pericles escapes leaving the laboratory to self-destruct, killing Cassidy Williams as the gang, Tom and Tub, and Scooby the Seal escape. Overarching Mystery Events: The lost original settlement of Crystal Cove, which vanished over three centuries ago, now submerged beneath the sea; its inhabitant missionaries were the conquistadors who were the source of Crystal Cove's curse; the base revealed to have been constructed by Frau Abigail Gluck, a member of an old mystery-solving group; her body whispers "Nibiru" upon its discovery; the final piece of the Planispheric Disk, found by Professor Pericles. Villain: Kriegstaffelbots and Sea Specter controlled by Professor Pericles Notes: Tom and Tub's parents are said to be Dr. Paul Williams and Captain Michael Murphy, which are characters from the Hanna-Barbera show Sealab 2020. Tom, Tub and Scooby the Seal appeared in the Hanna-Barbara series Moby Dick and Mighty Mightor. Their submarine, the Moby, is a reference to their whale friend Moby Dick from the same series. The title is a parody of The Twilight Zone.
38	12	"Scarebear"	Victor Cook	Erin Maher & Kathryn Reindl	August 14, 2012	September 25, 2012 (Poland) December 16, 2012 (UK) November 17, 2012 (Latin America)
A bear-like creature attacks Mayor Nettles and Sheriff Stone in the Crystal Cove woods near Destroido. They turn to the gang for help, explaining that the creature is called the Scarebear and has been stalking the grounds near Destroido for weeks. The gang finds out that the Destroido company has allowed toxic lithium to spill into the woods, which has resulted in the mutations of inhabitant plants and creatures including the Scarebear. Meanwhile, Mr. E and Professor Pericles have recruited Brad and Judy to help them find the gang's pieces of the Planispheric Disk, and have resorted to drastic measures to get the gang out of the way. Villain: Scarebear/Benson Fuhrman (Hairmore) Notes: The Scarebear footage shown to Mystery, Inc. parodies the Patterson–Gimlin film. Fuhrman's voice is an impersonation of Christopher Walken. Fuhrman said he got his claws from "a school for gifted children". This is a reference to Wolverine and Professor X's school in Marvel's X-Men franchise. Mr. E is discovered to own Destroido. Jeff Bennett voices Mr. E in this episode due to Lewis Black being unavailable at the time.
39	13	"Wrath of the Krampus"	Curt Geda	Michael F. Ryan	August 15, 2012	September 26, 2012 (Poland) November 24, 2012 (Latin America) December 17, 2012 (UK)
A teenager vandalising a neighborhood is attacked by a creature calling itself "Krampus", leaving his hair snow-white with fear. Three more kids are attacked as the gang meets Mayor Nettles and Sheriff Stone at the roller rink and arcade. Realizing that Krampus attacks "bad kids" such as the aforementioned teenager, the gang turns to the imprisoned Mary-Ann Gleardon for help, only to have Krampus attack and kidnap her. In the end, it's revealed that the gang had enrolled the forces of Hot Dog Water, Jason Wyatt, Mary-Ann Gleardon, the former Mayor Fred Jones Sr., and Charlie the Robot (from the Haunted Museum exhibition) in an elaborate scheme to steal the original Mystery Incorporated's pieces of the Planispheric Disk. The final scene shows the crystal sarcophagus found by the conquistadors emitting the word "Nibiru." Overarching Mystery Event: Velma finds that the word "Nibiru" (whispered by the specter of Frau Gluck in "The Midnight Zone") refers to an ancient Babylonian prophecy of a collision between Earth and a large planetary object known as "Planet X," whose inhabitants were the first recorded instances of gods. Villain: Krampus/Charlie the Robot, controlled by Jason Wyatt for Mystery Incorporated Notes: Besides Mary-Ann Gleardon, nearly all of the villains the gang has unmasked make cameo appearances in the prison, including Grady and Greta Gator, Alice May, Grandma Moonbeam, and Dan Fluunk. In the Haunted Museum, the Luna Ghost from the Scooby-Doo live-action film can be seen in the background as a statue. The Giggling Green Ghost from the Scooby-Doo, Where Are You! episode "A Night of Fright is No Delight" also makes a cameo appearance in the arcade game Sheriff Stone and Mayor Nettles are playing, which is a reference to The House of the Dead. Velma reads a description of the Nibiru cataclysm off of her "favorite internet encyclopedia." The description she reads is near word-for-word that of the Wikipedia article on the event.
40	14	"Heart of Evil"	Victor Cook	Jim Krieg	August 16, 2012	January 19, 2013 (UK) February 4, 2013 (Latin America)
Five years ago, a gigantic dragon robot attacks the Quest Industries, then promptly vanishes, leaving security guard Radley Crowne's dog Reggie unconscious. Dr. Benton Quest works to revive the dog. In the present day, the same robot attacks the gang at City Hall as they begin their investigation into the purpose of the Planispheric Disk. However, the gang is saved by Blue Falcon and Dynomutt who explain that they have been tracking the robot for years. Velma rudely tells the heroes that Crystal Cove is their turf and Blue Falcon offers the gang to tag along. Together, they find that Quest Industries has been sold to Destroido. Upon investigation, the dragon-robot attacks, intending to kidnap Dynomutt only to make off with Scooby-Doo instead. Using a tracking device located on Falcon's belt, the gang and Dynomutt are able to locate Dr. Zin's lair and save their friends. Overarching Mystery Event: Velma's primitive recorder, used on the Planispheric Disk, yields the word "Nibiru". Villains: Dragon Battle Suit/Jenny Zin, Dr. Zin Notes: Blue Falcon is depicted in the artistic style of Frank Miller's Batman from The Dark Knight Returns. Some of his lines of dialogue are either direct quotes or homages owing to that work. Dr. Zin. Jenny and their henchman Bobo also function as references to Batman enemies Ra's al Ghul, Talia al Ghul and Ubu. Ubu is Ra's al Ghul's chief henchman and Talia is frequently endangered by her father's schemes. Velma's primitive recorder resembles the speak-n-spell phone-home transmitter from E.T. the Extra-Terrestrial. Dr. Zin is the primary villain from Hanna-Barbera's Jonny Quest. The gang had previously appeared with Blue Falcon in several episodes of the Dynomutt, Dog Wonder segment of The Scooby-Doo/Dynomutt Hour in 1976. Later in 2013, Blue Falcon and Dynomutt would feature prominently in the direct-to-DVD film Scooby-Doo! Mask of the Blue Falcon.
41	15	"Theater of Doom"	Curt Geda	Joe Flaherty & Paul Rugg	August 17, 2012	January 20, 2013 (UK) February 11, 2013 (Latin America)
The Crystal Cove Haunted Historical Society performs reenactments of Crystal Cove history every year. During a rehearsal for this year's production revolving around Friar Gabriello Serra and his donkey Porto, a specter resembling one of the props scares off the cast and crew members. Vincent Van Ghoul, called upon to take over production, finds the set destroyed and calls in Mystery Incorporated who become the new cast and crew for the play. Meanwhile, Professor Pericles instructs Brad and Judy to steal the Planispheric Disk back from the gang. After solving the case, the gang encounters the real ghost of Friar Serra, who reveals that he was part of a mystery-solving group in the original Crystal Cove settlement, which became a victim of the Planispheric Disk, resulting in the destruction of the original Crystal Cove settlement caused by Friar Gabriello Serra's donkey. The ghost of Friar Serra warns of the coming of "Nibiru" and that "the dog must die" because the animal mascot always starts the downfall. Overarching Mystery Events: It is revealed that Friar Gabriello Serra's corrupted donkey Porto sent the original Crystal Cove settlement into the ocean, not an earthquake as was originally believed. The Phantom Mummy of Friar Serra warns the gang about evoking the memory of "Nibiru". Friar Serra's statement of "Heed the warning of the alligators" is a reference to the hotel sign in Gatorsburg reading "The dog dies!" in "The Creeping Creatures". Villain: Phantom Mummy of Friar Serra/George Avocados Note: Upon his capture, George Avocados reveals that the crystal which the Ghost Trucker was seeking in "The Secret of the Ghost Rig" was actually disguised as a doorknob in the Burlington Library, and belonged to the Avocados family. As Vincent Van Ghoul begins the production in front of the audience, he performs an homage to Vincent Price's part in Michael Jackson's Thriller.
42	16	"Aliens Among Us"	Victor Cook	Erin Maher & Kathryn Reindl	March 25, 2013	January 24, 2013 (New Zealand) February 18, 2013 (Latin America) March 3, 2013 (Canada)
Sheriff Stone bursts in as the gang are investigating the Planispheric Disk and claims to have remembered a childhood experience wherein he was abducted by aliens. As the gang investigates Sheriff Stone's claims, real extraterrestrials consisting of a Grey Alien, a Nordic Alien, and a Reptoid, begin stealing valuable items from Crystal Cove. As Velma, Shaggy and Scooby investigate, the Blake home is attacked and Barty's new car is stolen. The gang reunites to solve the mystery. Meanwhile, just after returning from Gatorsburg, the gang discovers that their office, located in the City Hall, has been set ablaze, and the arsonists are revealed to be Brad Chiles and Judy Reeves. Overarching Mystery Events: Velma's primitive recorder, used on the Planispheric Disk, yields the phrase "Señor P. Llave", and the coordinates to the Gatorsburg cemetery; upon reaching Señor Llave's grave, the gang find it empty, with only an old flintlock left in it. Villains: Grey Alien/Traveler O'Flaherty, Nordic Alien/Sheela O'Flaherty, Reptoid/Connor O'Flaherty Note: The coordinates for the Gatorsburg cemetery are coordinates for a Warner Bros. studio in real life. Also, the coordinates to the Gatorsburg cemetery allude to Mr. E's note in "The Creeping Creatures" stating that Gatorsburg was "one piece of the puzzle". The scene where the Mystery Machine breaks down is an homage to Close Encounters of the Third Kind, while the cornfield sequence is an homage to Signs. The lines about a group of reptilian creatures living in the center of the Earth may be a reference to the Silurians from Doctor Who.
43	17	"The Horrible Herd"	Curt Geda	Michael F. Ryan	March 25, 2013	February 25, 2013 (Latin America) March 10, 2013 (Canada)
Professor Pericles creates a herd of mutant cattle (which he had bred from cattle, piranhas, and bees) to destroy Crystal Cove in an attempt to locate the Planispheric Disk. As the herd begins devouring the town, the gang, Mayor Nettles, and Sheriff Stone use Ex-Mayor Jones' helicopter to trap the herd's queen. The cattle follow the gang as they leave town with the queen in tow in an attempt to protect her. Watching from afar, Professor Pericles orders Brad and Judy to shoot the helicopter down. The missile strikes the chopper and as Mayor Nettles attempts to land safely, Nova falls out and is nearly trampled to death by the herd. The queen cattle is dropped into the ocean as the herd scatters throughout the ocean. Scooby-Doo then has everyone get Nova to the hospital. Villains: Skull Cattle created by Professor Pericles Note: The farmer attacked by the Skull Cattle at the beginning of the episode is the same farmer who held Scooby captive at the pound in "The Night the Clown Cried", which is why the two reacted to each other's presence with hostility. Nova's fall from the helicopter is animated in a similar fashion to Mufasa's fall in The Lion King.
44	18	"Dance of the Undead"	Curt Geda	Benjamin Townsend	March 26, 2013	March 1, 2013 (Latin America) March 17, 2013 (Canada)
Since her accident with the herd, Scooby has been visiting Nova regularly in the hospital. Meanwhile, a deceased ska band returns from the grave and hypnotizes partygoers at the local nightclub to dance to their music. The dancers are taken to hospital, whereupon the gang is called to solve the mystery before they dance themselves to death. Eventually, the band hypnotizes Fred and the girls, forcing Scooby and Shaggy to turn to the Hex Girls for help. Overarching Mystery Events: The gang discovers a musical phrase which has appeared on the Planispheric Disk. When the Hex Girls sing the phrase, the Disk reveals another set of coordinates, which leads the gang to the restaurant owned by Skipper Shelton, whereupon they find that his hat (given to him by Handsome Jimmy from "Night on Haunted Mountain") bears the name "S. Llave" written under the brim. Scooby visits Nova in the hospital, only to see her flatline. Just afterward, she sits up in bed and says "Nibiru. Nibiru is coming", before regaining life. Villains: Ska Zombies/Rude Boy and the Ska-Tastics Notes: This is the second appearance of the Hex Girls, who have converted back to their original outfits as seen in Scooby-Doo! and the Witch's Ghost. The song "Who Do Voodoo?" from Scooby-Doo! and the Legend of the Vampire is featured in this episode. The song "Stuck in My Throat" is also heard once more, as it was last featured in "Battle of the Humungonauts". This episode shows many similarities Scooby-Doo! and the Legend of the Vampire; both have a band that has disappeared, and musicians being kidnapped. Martha Quinn plays herself, as the owner of Grooves from the Grave. The battle between the Ska Zombies and the Hex Girls is reminiscent of a scene in Scott Pilgrim vs. the World, where the music from two rival bands generates monsters that start fighting each other; the winning monster wins the music competition. Music for Rude Boy and the Ska-Tastics was written and performed by Dave Wakeling of The English Beat. Cass Elliot is one of the dancing people at the Tiki Tub.
45	19	"The Devouring"	Victor Cook	Michael F. Ryan	March 27, 2013	March 8, 2013 (Latin America) March 23, 2013 (Canada)
A gluttonous monster attacks Francilee Jackson on her cooking show. As the gang attempts to eat dinner together, the restaurant is crashed by Rick Spartan and Cachinga, who are on the hunt for the monster. The monster attacks various locations around Crystal Cove, including various restaurants and the museum where Velma's mom works. Meanwhile, Professor Pericles has gone crazy, leaving Mr. E to attempt to seek the treasure without him. Brad and Judy tell Pericles of E's mutiny, and Pericles uses venom injections to force Mr. E to work for him. Overarching Mystery Events: Francilee Jackson drops her bowl as she is escorted away and the bowl is revealed to bear the words "Tercera Llave" on its underside. Villain: Gluten Demon/Francilee Jackson Note: This is the second appearance of Francilee Jackson, as she last appeared in the episode "Web of the Dreamweaver!", where she was also a suspect. This is also the second appearance of Rick Spartan and Cachinga, who both last appeared in the episode "Attack of the Headless Horror".
46	20	"Stand and Deliver"	Victor Cook	Caroline Farah	March 28, 2013	March 15, 2013 (Latin America) March 30, 2013 (Canada)
A family vacationing in the mountains near Crystal Cove is attacked by a polite Englishman in a mask calling himself the Dandy Highwayman, who blows up the family's station wagon and leaves with the mother. Later, the gang stumbles upon the wreckage of several cars on the mountain roads and decides to investigate. As they investigate, the Highwayman kidnaps several women from around Crystal Cove, including Mayor Nettles, Daphne, and Mrs. Blake, and steals all of the money from the Blake safe. With inside help from Daphne (who is safe and sound in the Highwayman's lair), the gang traps the Highwayman and solves the mystery. Overarching Mystery Events: While the gang is researching the Dandy Highwayman in the town library, Scooby awakes from another nightmare and knocks the book he is reading off of the table, dislodging a piece of cloth from within the book which bears the words "Cuarto Llave" written on it. Scooby has been having nightmares since Nova's accident. In Scooby's latest nightmare, a being speaking through Nova warns him of the coming of the Anunnaki at the time of Nibiru and warns him that his life is in danger, telling him that he and his friends must destroy the cursed treasure beneath Crystal Cove. Scooby then informs his friends about his dream. Villain: Dandy Highwayman/Crystal Cove Librarian Note: The family travelling on the Crystal Cove highway is the same family that was vacationing in the episodes "Night Terrors" and "The Creeping Creatures". Also, Scooby's first dream is a reference to the dream sequence An American Werewolf in London and the second dream is a reference to Twin Peaks. The Dandy Highwayman character is an homage to the Monty Python character Dennis Moore; a robber who uses the line "Stand and Deliver" when holding up his victims. "I'm the Dandy Highwayman" are the opening lyrics of the Adam and the Ants song, "Stand and Deliver", the group's most successful single.
47	21	"The Man in the Mirror"	Curt Geda	Jim Kreig	March 29, 2013	March 22, 2013 (Latin America) April 6, 2013 (Canada)
As the gang investigates a haunted house, a man resembling Fred pulls Fred through a mirror and takes him to a world where the Planispheric Disk destroyed all of Crystal Cove. Meanwhile, in the real world, Fred begins acting strangely. The real Fred manages to tell the gang that the Fred in their world is fake, having discovered so when a fake Daphne in the "mirror world" gave herself away. When the ruse is discovered, Professor Pericles uses the Kriegstaffelbots to threaten Daphne in order for the Planispheric Disk to be surrendered to him. When Professor Pericles gets the Planispheric Disk, he makes plans to free his "master". Overarching Mystery Events: Professor Pericles appears to be serving the Evil Entity sealed within the crystal sarcophagus, and has been on a mission to gain access to the Planispheric Disk in order to set the being free. Villains: Fake Fred/Brad Chiles, Fake Daphne/Judy Reeves, Kriegstaffelbots Note: The apocalyptic setting in the mirror world parodies the 1984 horror classic Night of the Comet.

When a monstrous version of the Freak of Crystal Cove begins appearing in Scooby's nightmares, the gang decides to investigate what's going on. They seek the help of the reclusive hypnotist Professor Horatio Kharon (author of the book Velma has been reading), who has also been seeing the Freak within his dreams as well as appearing in Scooby's. After being hypnotized to enter the dream world, the gang is chased by the Monstrous Freak throughout the dimension. They soon discover the evil entity that was trapped with the cursed treasure, and how previous mystery groups and the people affiliated with the treasure have been manipulated by the entity. The being speaking through Nova tells Mystery Incorporated that they must find the Heart of the Jaguar in order to destroy the Evil Entity sealed within the crystal sarcophagus. Overarching Mystery Events: The good personality components of all members of previous mystery groups and the people associated with the cursed treasure (among them ex-Mayor Fred Jones Sr., Ed Machine, Cassidy Williams, Ricky Owens, Brad Chiles and Judy Reeves) were sent to the dream dimension where they remained to stay. The very first mystery group, the Hunters of Secrets, was first manipulated by the entity within the sarcophagus; however, they were pure and realized they were being manipulated. They attempted to destroy the entity with a relic referred to as the "Heart of the Jaguar", but never succeeded due to the conquistadors' interruption. The Keys are being used by previous mystery groups (such as the Darrow Family, the Alianza Mysterio, the Fraternitas Mysterium, the Mystery Gang, and the Benevolent Lodge of Mystery) when the gang visits them in the dream world, symbolizing their use with the gates to the cursed treasure. If they destroy the entity, everyone from the dream world would be set free from the curse. Villain: Monstrous Freak/The Ghost of Fernando El Aguirre Note: This episode parodies the A Nightmare on Elm Street franchise; in this episode, if the gang had gotten trapped they would never wake up, while in the movies, if the character Freddy Krueger killed the kids in their dreams they would die for real. The room with red curtains is almost identical to the one from Twin Peaks. The "dancing" Horatio Kharon resembles The Man from Another Place from Twin Peaks, and is voiced by the actor who played that role in the series, Michael J. Anderson. The house in which Horatio Kharon lives resembles the one in the original Scooby-Doo, Where Are You? season one opening from 1969.
49	23	"Dark Night of the Hunters"	Michael Goguen	Benjamin Townsend	April 3, 2013	April 5, 2013 (Latin America) April 20, 2013 (Canada)
The gang, accompanied by Velma's mom, goes to Yucatán in an attempt to search for the Heart of the Jaguar after Angie's old friend, Professor Enrique Andelusossa, is "consumed by the jungle" near the Temple of the Hunters (the burial site of the Hunters of Secrets where the Heart of the Jaguar is kept). Upon arriving in Yucatán, the gang visits Professor Enrique's antique shop, where they are greeted by his angry wife, who says Mrs. Dinkley is to blame for his disappearance. After hours, the gang returns to the store, only to be attacked by the Mayan Priestess, who warns them away from the temple. The gang ignores her threat and travels into the jungle to find the temple. Due to Fred's master trap skills, Mystery Incorporated overcomes the temple's diabolical traps and discovers the Heart of the Jaguar in the tomb. The Priestess attacks, but fails and is captured by the traps in the temple, which she triggered. Afterwards, Lieutenant Tomina Kasanski (a woman who had been spying on the gang) appears, but is revealed to be working with Mayor Nettles. Overarching Mystery Events: The gang finds the Heart of the Jaguar, the spear used by the Hunters of Secrets that is able to destroy the evil entity trapped in the crystal sarcophagus. Mayor Nettles had a nightmare telling her that the gang would need her help in transporting the Heart of the Jaguar back to Crystal Cove. Villain: Mayan Priestess/Professor Enrique Andelusossa Note: The Mayan Priestess attacks her victims with a vicious, flowering, sentient plant, an homage to the creature in The Ruins. The traps throughout the episode are an homage to the Indiana Jones franchise, with the blow darts and crushing walls from Raiders of the Lost Ark, and the "breath activated" buzz saw trap from Indiana Jones and the Last Crusade.

Once the gang returns to Crystal Cove, they find out that everyone in town has disappeared below ground. Later that day, after witnessing Mayor Nettles and Sheriff Stone vanish, the gang goes to Fred's house to discuss the Planispheric Disc, Nibiru, the cursed treasure, and an upcoming planetary alignment. After the interruption of Kriegstaffelbots, the gang sets off beneath Crystal Cove, and discovers everyone in town working for Professor Pericles and the rest of the original Mystery Incorporated. After hearing a conversation between the old Mystery, Inc., the gang is convinced they have gone crazy, and devise a tactical plan to bust everyone out and shut down the operation. Shaggy and Scooby go undercover as Kriegstaffelbots, while Fred and the girls attack in a suited-up Mystery Machine. After the word is spread, Sheriff Stone has everyone rebel against the Kriegstaffelbots and go on a riot. Soon, the Kriegstaffelbots stop Fred, Velma, and Daphne in their tracks, forcing them to blow up the Mystery Machine (in which everyone thought they were). After all is resolved and the doorway is opened to the cursed treasure, the gang gears up with the relics and follows the original Mystery Incorporated into the caverns. Overarching Mystery Events: The passageway to the cursed treasure is found and opened. Professor Pericles confirms Cassidy's death to a troubled Mr. E, who is worried about her and is saying she was right the entire time. Velma's computer model of the Planispheric Disc perfectly mirrors the planets in the solar system. The planets are coming into direct alignment and the tenth planet, Planet X, is getting closer and is about to come into alignment behind Pluto and will cause a massive gravitational disruption, one not seen in 5,000 years. The time of Nibiru happens in two days. The gravitational disruption makes the fabric between dimensions of time and space weak, which is why the evil entity buried beneath Crystal Cove must be destroyed. Along with destroying the entity, the Heart of the Jaguar will undo all of its evil. Villains: Professor Pericles, Brad Chiles, Judy Reeves, Mr. E, and the Kriegstaffelbots Note: Before the interruption of the Kriegstaffelbots, the mysterious being burrowing and sucking its victims into the ground is an homage to the movie Tremors, as the monster in that movie is a subterranean worm that hunts based on sound and movement. Brad and Judy still resemble Fred and Daphne since "The Man in the Mirror", since Professor Pericles won't allow time for the reversal procedure. The destruction of the Mystery Machine is very similar to the destruction of the Enterprise in Star Trek III: The Search for Spock. The dialogue was a direct homage to that scene.
51	25	"Through the Curtain"	Michael Goguen	Michael F. Ryan	April 5, 2013	April 19, 2013 (Latin America) May 4, 2013 (Canada)
As the gang follows the original Mystery, Inc. through the caverns, they all approach the first gate to the cursed treasure. Professor Pericles knows the gang has been following them, as he calls them out to bring the Keys in order to open the gates. The gang realizes that the Keys and their scenarios seen in the dream world is how they all apply to the gates and the gates being opened. The gang decides to cooperate, after Pericles reveals that they have Hot Dog Water, and opens the first gate. Thanks to Hot Dog Water, the gang enters the first gate; however, Hot Dog Water is killed by the Kriegstaffelbots nearly straight afterwards. The gang arrives at the second gate, and opens it using the mortar bowl. They enter a mysterious rock dimension, where they are greeted and chased by a Rock Monster. After the monster's failure, the gang comes before the third gate, which is opened using the conquistador's helmet. The gate then releases water trapped behind and turns into a boat, allowing Scooby and the gang to escape and become stranded at sea. After learning that the next gate is below the water, the gang comes upon the final gate, which is opened using the flintlock. The gang enters the dimension, which is teeming with lava, and come upon the crystal sarcophagus and cursed treasure, realizing that they are beneath Crystal Cove. The Evil Entity sealed within tries to manipulate the gang into opening the sarcophagus to free it, but the gang realizes the words the being is speaking aren't true. Suddenly, Pericles and the original Mystery Incorporated arrive and Pericles opens the sarcophagus, releasing the Evil Entity. Overarching Mystery Event: The Evil Entity which was sealed in the crystal sarcophagus is released from its imprisonment. It tells the gang that it brought them together as it brought together those groups before them, solely for the purpose of releasing it; the gang realizes that everything the Entity is saying is untrue. Villains: Professor Pericles, Mr. E, Brad Chiles, Judy Reeves, Kriegstaffelbots, Rock Monster, Evil Entity Note: When Scooby-Doo and Shaggy are running down the side of the mountain away from the Rock Monster, their animations are exactly like their classic run cycle animations seen in Scooby-Doo, Where Are You!.
52	26	"Come Undone"	Victor Cook	Michael F. Ryan	April 5, 2013	April 26, 2013 (Latin America) May 11, 2013 (Canada)
The gang and original Mystery Incorporated stand before the Evil Entity. The Entity grabs Scooby-Doo, and mentions that he must die and be reborn as a vessel for its darkness. Scooby breaks free, but Pericles volunteers to be possessed by the being, to which the Entity agrees. Professor Pericles believes he has gained ultimate power (due to his growth in size and appearance), but the Evil Entity kills Pericles and mutates his body into a squid-like monster. The Entity then assumes control of the Kriegstaffelbots and summons other evil Anunnaki, who proceed to offer the townspeople for the Entity to consume. When Scooby destroys the sarcophagus, a vortex opens and sucks in and destroys the Entity, his minions, and much of the rest of Crystal Cove, except for the gang, then explodes. The gang find themselves in a new version of Crystal Cove and Earth itself. After some strange encounters, Mystery Incorporated realizes that all the evil ever caused by the Entity has come undone, thereby changing history. The gang sets up a new Mystery Machine and travels off to their new destination after receiving a message from Harlan Ellison, vowing to solve each mystery they come across. As the gang drives away, they are watched by Nova, who says Scooby is the bravest dog that ever lived and thanks him and the gang. Overarching Mystery Events: The overall mystery is solved. By destroying the Evil Entity, the gang created an entirely different timeline. No one has been negatively influenced by the Evil Entity. Everything has come undone; the gang's actions have created a perfect world where they live productive and normal lives. Harlan Ellison, who is now called Mr. E, contacts the gang and tells them he knows who they are. He knows that they created an alternate timeline by destroying the Evil Entity, due to him being a genius and his hypertuned psychic and hypnotic connections with alternate dimensions, which is why he is able to remember every timeline ever created. However, he mentions that the gang has slipped the timestream with him. He has admitted the gang (including Scooby) to be in his class next semester and he mentions there is a lot of meddling to do and a lot of mysteries to be solved. Villains: Evil Entity, Kriegstaffelbots, the Entity's Anunnaki slaves Notes: This episode is the second appearance of Harlan Ellison, who was last seen in "The Shrieking Madness". When the gang is running away from the Anunnaki, their animations are similar to their classic run cycle animations seen in Scooby-Doo, Where Are You!. The gestures the gang makes upon returning to Crystal Cove are the same gestures they made at the beginning of "Beware the Beast from Below". A laugh track followed by applause is featured when the gang is driving off at the end of the episode. Unlike any other episode in the series, the end credits feature the opening theme and a background resembling the paintjob of the Mystery Machine.
