Premise[]
Life for the Gang is boring after they take down the mastermind behind many of their greatest villains. But suddenly they are attacked by doppelgangers of themselves! Can Scooby-Doo and the Gang solve the mystery after many of their old foes run amok in Coolsville at Halloween?
Synopsis[]
Mystery Inc. is at a ski resort in Kathmandu, Nepal solving the mystery of the Cat Man, Shaggy and Scooby-Doo slide down a mountain on a snowboard to lure the Cat Man into a trap, when the time comes, Fred tells Velma to activate a laser and Daphne makes it bounce with her pocket mirror and they attract Cat Man's attention, make him attack some Shaggy and Scooby snowmen and when he discovers that they are made of snow, he gets angry and growls, the noise causes an avalanche that drags the Cat Man to the base of the mountain and he is trapped.
The people and an inspector celebrate Mystery Inc. and unmask Cat Man as Olive Kahdka, the daughter of the owner of the ski resort, it turns out that her father planned to leave everything to his new wife, Heena (who is half his age), but the meddling kids leave quickly to analyze Cat Man costume, Mystery Inc. discovers that Cat Man's costume is made of the same materials as costumes of the other criminals they caught, such as Spooky Space Kook/Henry Bascomb, the Ghost of Captain Cutler/Captain Cutler, Ghost Clown/Harry the Hypnotist and it all started with the Black Knight/Mr. Wickles, Mystery Inc. discovers that all the costumes were created by the same person, a costume designer and criminal mastermind named Coco Diablo.
During Halloween at Diablo Costumes (Coco's factory), safe and excellent quality costumes are made, Coco receives a client and gives him a VIP tour, Coco shows him the factory and how they make costumes, but then Trevor, Miss Diablo's apprentice, shows her the Dracula costume he made but Coco complains that he always makes the same costume and throw it into a crocodile pit, making Trevor cry, Coco continues with the tour when the client tells her that he wants to see something more terrifying (referring to a monster costume to commit a crime), Coco understands what he says and they enter Coco's Office (a demon head that is lowered and raised from the ceiling) together with Coco's cat, Esteban.
The client tells Coco that Olive told him about her disguises and Coco laments that all the criminals used their disguises and were defeated by Mystery Inc. but is grateful that they recommended her, the client explains that he heard about a new highway and Coco realizes that he wants to buy the cheap land to make a lot of money but first he needs to get rid of the competition, then Coco and Esteban offer him Coco's best creation, the 10,000 Volt Ghost. the customer asks how much the costume costs, to which Coco tells him that he can keep it for free and only asks that in exchange he get rid of the meddling kids for having destroyed all her costumes and Esteban asks him to also get rid of Scooby, calling him "dumb dog", but then the client reveals that he is actually Shaggy and Scooby, the office opens revealing Fred, Daphne and Velma along with the Sheriff. Fred congratulates Shaggy and Scooby on their work and Velma proceeds to give them Scooby Snacks but upon seeing Coco she falls in love with her and gets distracted, the Sheriff thanks the gang for helping them catch Coco and Fred explains that they did it thanks to their teamwork, with Shaggy and Scooby gathering clues and Velma analyzing the data, but Fred doesn't know what to say about Daphne and neither does she, Coco tells the gang about having too much of a good thing and the Sheriff takes her away, as they leave they are greeted by cameramen and Coco tells them to take photos, stating that all press is good press, the gang leaves having solved the mystery and with Coco Diablo in prison things will be calmer.
With Coco Diablo in prison, Coolsville becomes peaceful since the criminals cannot get the costumes they need to commit their crimes, which means that for a whole year the gang has no exciting mysteries, so they dedicate themselves to solving simple and boring mysteries, such as finding rats eating packets of nuts at a grocery shop, helping a man fix his car lock remote, rescuing a cat from a tree, finding a scruffy man's missing sock, retrieving a boy's ball from a graveyard and unclogging hair from a bathtub, Fred, Daphne and Velma grew depressed by the lack of solving real mysteries, while Shaggy and Scooby enjoy a much better time relaxing due to the lack of danger. After solving a tax scheme, only for the culprit to escape, Fred goes to the town's wishing well and makes a wish for more mysteries. Meanwhile, Shaggy and Scooby prepare themselves for trick or treating on Halloween.
While attending a local carnival, the gang were suddenly attacked by a ghoulish lookalike of Fred who blew up the Mystery Machine with his blasts. Thinking Coco is behind it, the gang head to Coolsville Penitentiary to interview her. After meeting Warden Collins who was a big fan of the gang, Coco was allowed to go with them, and Collins attaches two heart monitors to Velma and Coco's wrists to make sure Coco doesn't escape. The gang head to the carnival in the wrecked Mystery Machine to find anything linked to the ghost attack.
Arriving at the carnival, now in ruins, the gang find a clue in the remains of their booth and head to the library where they do research on the mysterious ghosts who resemble the gang and call themselves Misery Company. Suddenly, the gang were attacked by the Fred lookalike ghost, along with ghosts who resemble Daphne, Velma, Shaggy and Scooby, but they escaped the attack. Thinking that Coco's former assistant, Trevor Glume, might be the culprit, the gang and Coco head to his shop he had opened after Coco's arrest. Confronting Trevor, Coco asked him about the ghosts' costumes that matched his style, and Trevor reveals that he sold four Victorian-era style costumes to Coolsville Penitentiary.
After Trevor proved his innocence to the gang, Coco escapes to her factory, breaking her heart monitor off her wrist while everyone was distracted. With help from Trevor, the gang rebuild and redesigned the Mystery Machine into the Gloomy Mystery Machine and followed Coco back to her factory. Arriving at the factory, the gang trapped the ghosts by dropping them into the alligator pit revealing themselves to be robots. When Coco offers a false confession, the gang saw through it and realizes that Warden Collins is the culprit behind the whole thing and he is holding Coco's cat, Esteban, hostage.
Heading back to Coolsville Penitentiary, the gang confront Collins who confesses that he was the one who built and operated the robots, admits that he did it after the gang had no more mysteries to solve after Coco's arrest. After assuring the gang that they're not in real danger, Collins accidentally turned off the security system, freeing the past villains from their cells, leaving them to cause havoc.
Coming up with a plan to round-up all the inmates, the gang dressed themselves in the past costumes from their old cases, and re-capture all the villains, and Collins was apprehended and arrested by the sheriff. Shaggy and Scooby reluctantly return the stolen candy to the trick-or-treaters, and Trevor gave the duo a big sack of candy and reveals himself to be a surfer using his Trevor disguise, while Coco was unwillingly taken back into custody along with Esteban.
The movie ends with the gang walking over the town's well and share a laugh over their adventure and a monstrous eye opens at the bottom of the well.

Notes/Trivia[]
- The movie was released on five dates in October 2022:
- Digital download on October 4
- New York Comic Con on October 7
- Cartoon Network on October 14
- HBO Max on October 15, and
- DVD on October 18.
- It is the first DTV to use the animation style of Scooby-Doo and Guess Who?
- The name Coco Diablo appears to be partially based on legendary fashion designer Coco Chanel. Just as Coco Diablo is jailed for enabling criminals, Coco Chanel was suspected of betraying France to the Nazis, but was never formally charged.
- Coolsville (first mentioned in A Pup Named Scooby-Doo) has been restored as the gang's hometown, whereas in the previous few DTVs, their Mystery Incorporated counterparts' hometown was Crystal Cove from Scooby-Doo! Mystery Incorporated. The general unwritten rule is that Coolsville is used in lighthearted versions, while Crystal Cove is used in stories with a darker tone.
- One of the costumes in Trevor's shop is Freddy Krueger's outfit from A Nightmare on Elm Street horror film franchise.
- This is the first time Velma is portrayed as explicitly non-heterosexual, as demonstrated by her attraction to Coco Diablo.
- This is one of the Scooby-Doo! DTV movies to not to include Andy Sturmer as a song writer or a song performer.
- The first official Scooby-Doo material to allude to the fact that some of the Scooby-Doo villains' costumes were created by a common manufacturer was DC Comics' "Costume Caper!". In it, the villains had mail-ordered their costumes from the Horne Costume Company, run by Harriet Horne (a woman company owner, much like Coco Diablo).
Animation errors/technical glitches[]
- During the chase scene in the library, there is a brief moment where Coco's turtleneck is purple instead of it's usual maroon-red color.
Inconsistencies/continuity errors and/or goofs/oddities[]
- This movie suggests that all the past villains now incarcerated in the Coolsville Penitentiary were operating and arrested in Coolsville, which is simply not correct. The localities of these villains varried.
- The prison scene featured Sarah Jenkins in prison, but in "Foul Play in Funland", she wasn't arrested for sabotaging Charlie the Robot. In fact, her brother, as well as the Scooby gang, agreed that, for safety reasons, Charlie was not fit to control a place where kids came to have fun.
- Then again, Charlie was seen active again in "Scooby-Doo and Guess Who?"
- Igor was even seen with the other prisoners, even though he wasn't arrested in the episode A Halloween Hassle at Dracula's Castle. He was praised by the monsters for doing something evil.
