Scooby-Doo on Zombie Island


 * This article is about the film. For other uses, see Scooby-Doo on Zombie Island (disambiguation).

Scooby-Doo on Zombie Island is the first in a series of direct-to-video films based upon Hanna-Barbera's Scooby-Doo Saturday morning cartoons. It was released on VHS on September 22, 1998.

It was the first movie to feature real monsters instead of traditional 'bad guys' in masks. This was heavily promoted before its release including a tagline used during commercials stating, "This time, the monsters are real." This theme would be followed up in several subsequent direct-to-video animated films released in the late-1990s and early-2000s. Although real monsters had previously appeared in most of the 1980s Scooby-Doo series and features, this continuity was ignored with the characters said to be encountering real monsters for the first time. After, the direct-to-video Scooby-Doo movies would not feature real monsters again until ten years later in.

Premise
The Mystery Inc. team split up to do their own thing but come together again to solve a real ghost mystery. The gang of sleuths gets more than they bargained for when, on Moonscar Island in the Louisiana bayou, they find themselves amongst worshiping un-dead werecats and a swarm of zombies.

Synopsis
Daphne is on a talk show to promote her mystery-travel series, Coast to Coast with Daphne Blake, during which she tells the hostess, Chris, about a past Mystery Inc. case when she was younger. At a faraway castle, Shaggy and Scooby are shown to be chased by a large moat monster. The gang had all been previously searching the castle for clues. As Scooby comes crashing down on the monster, the monster is discovered to be Mr. Beeman, a real estate agent. Beeman had been printing counterfeit money. Daphne explains how it was one of her most frightening mysteries. She also discusses her new show in which she plans to find real monsters.

Scooby and Shaggy, have taken up work as contraband security guards at a local airport. Unfortunately, they are exposed to a lot of tantalizing foreign food, and are unable to resist eating all the contraband. As a result, they are fired from their job.

Fred secretly contacts Velma who is now a book shop owner about going on a big trip for Daphne's birthday. Fred also secretly contacts Shaggy and Scooby. He picks them all up on the way to Daphne's home. Daphne is surprised to find the whole gang all with Fred. He explains how they can all search for ghosts together just like old times.

The gang decides to go to New Orleans for the first segment of the television program. They meet up with many fake ghosts such as a floating ghost which was just a video projection, a vampire bat who was just an old man stealing a necklace, a ghostly casino riverboat captain who was really an old lady, and lastly a lobster-man in a factory who was really a middle-aged man. Daphne is very disappointed to not find a real ghost. As Scooby and Shaggy look for food from local shops, Daphne, Fred and Velma meet a young chef named Lena. Lena had overheard Daphne's disappointment and says that a real ghost named haunts the island she works at. Velma looks up the island on her computer and agrees that there had been many strange disappearances on Lena's island. They agree to follow Lena back to her island.

The gang all express their excitement about visiting the island on the car trip down to the ferry. Real ghosts, homemade Cajun food and the beautiful scenery. The gang meets Jacques, the ferry driver for Moonscar Island and they board the ferry. Fred begins to videotape the bayou and Jacques discuss how pirates used to use the bayou to hide from the law, including Morgan Moonscar. Soon, Scooby and Shaggy accidentally fall off the ferry trying to catch a catfish named Big Mona. Alligators chase them but they are rescued by an angry fisherman named Snakebite Scruggs and hunting pig Mojo. Shaggy and Scooby board the ferry again. They reach Moonscar Island and drive off the ferry. Jacques leaves back toward New Orleans. As the gang approaches Simone's house, who is the owner of the plantation Lena works at, they notice all the cats around the porch area. Scooby chases the cats and causes a big commotion, angering Beau the gardener and Simone the house owner. Daphne introduces herself to Simone and they discuss the plantation and its ghosts. Simone agrees that it is haunted by “restless spirits.” She agrees to Daphne recording around the plantation. They all enter the mansion except the cats and the gardener.

Scooby and Shaggy give the rest of the gang a scare after screaming loud. They had simply been surprised by how hot the plantation's peppers were. After Simone, Lena and the rest of the gang leave, Scooby and Shaggy scream again but this time it is because of ghostwriting on the wall that appeared suddenly. Daphne excitedly tapes the wall and another word appears while taping, carved into the wall suddenly. Viewing the tape later in slow-motion, the gang discovers that the writing was done by the ghost of Morgan Moonscar. Scooby and Shaggy get hungry and make a huge picnic basket of food. Velma returns to the wall to see what is under the wall paint. She uses a spatula to peel off all the paint behind the ghostly words written by the ghost. She discovers a piece of Morgan Moonscar's ship which was used in the construction of the mansion. Simone and Lena aren't surprised.

Scooby and Shaggy get into mischief with Simone's cats and Mojo the hunting pig. They fall into a hole which they later discover is a grave. As they try to exit the grave, they pull off a piece of the wall and a skeleton hand falls from a hole in the side of the wall. Above them, a sinister-looking green fog-like energy manifests and envelopes the entire skeleton. It begins to gain skin, clothing and hair, and morphs into the zombie of Morgan Moonscar himself, and it begins to chase Scooby and Shaggy who escape the grave and run for their lives. They run into Beau the gardener but can't find the zombie afterward. The gang goes back to investigate the grave but it is found to be empty. It starts to get dark and Simone offers for the gang to stay at her home for the night. They agree.

Lena quickly but kindly shows the gang around to their individual rooms. Shaggy, who is excited about dinner gets dressed and trims his beard. Scooby plays with an owl just outside the window. As Shaggy stares into the mirror, a Civil War ghost comes out of the mirror and tries to warn Shaggy telling him to “get away”, just as the ghost of Morgan Moonscar had tried to warn the gang by his message in the kitchen. Velma investigates the mirror and agrees that it is from the Civil War era. Everyone leaves for dinner. At dinner, Scooby causes trouble with the cats again. He and Shaggy have to eat a crawfish boil outside in the Mystery Machine. They enjoy the Cajun meal until the cats follow them to the mystery machine and all stare at them through the windows. Shaggy drives the Mystery Machine away in order to shake off the cats. Meanwhile, Fred, Daphne, and Velma discuss over Simone's dinner table why someone in a pirate mask would want to scare everyone off the island. Treasure? Oil under the island?

Back in the Mystery Machine, Scooby and Shaggy dare each other to eat one of the hot peppers. Soon they both go running to a nearby lake for a large drink of water. As they drink, the mysterious green fog reappears and feeds its spirit at the bottom of the lake. Zombies start to rise up from the floor of the lake. Soon, zombies are rising from every location around. Shaggy and Scooby get in the Mystery Machine and try to drive away but get stuck in the mud. They meet up with Beau but mistake him for a zombie and keep running toward the house. Inside, everyone hears Scooby and Shaggy yelling. Lena grabs lanterns for the gang to use as they head out to look for Shaggy and Scooby. They meet up with Beau and suspect that he might have to do with the Zombies. Daphne suggests that they all split up and look for Scooby and Shaggy.

After some searching, Daphne and Fred find the abandoned Mystery Machine. As they investigate around, they find a zombie along with Shaggy and Scooby. Daphne karate-throws the zombie onto the ground and it stops moving. Daphne tapes as Fred tries to remove the zombie mask. He accidentally pulls the zombie's real head off. They realize the zombie could be real. The malevolent green fog again hits the lake and stirs up more zombies rising from the ground. As Fred records, the zombies get closer, starting to surround Fred and Daphne. They run away but lose the camera in quicksand. Scooby and Shaggy have already been running and they scream in fright as they look for any safe place away from all the zombies. The zombies look like they are from different eras and backgrounds. Some have modern cameras around their necks and tourist clothes on while others are dressed as pirates, Confederate soldiers and even gangsters in elegant suits.

Shaggy and Scooby fall into a cave and find voodoo dolls of Velma, Daphne, and Fred. As they begin to play with the dolls, the actions the dolls do are connected to the real-life actions of the gang. Faraway, the rest of the gang begins to float and kick each other as their bodies are controlled by the voodoo dolls. Bats scare Scooby and Shaggy out of the cave and they are again chased by zombies.

Velma, Beau, Fred and Daphne go back to the mansion to look around. The power is out. Also, the staircase leading upstairs has been lifted up, with a tunnel going down beneath. Fred finds Lena there who says that she and Simone were attacked by the zombies. The zombies had supposedly grabbed Simone and dragged her away down the tunnel. They all head down the tunnel, Velma leading the way by following footprints on the ground. They all enter a voodoo ritual room. Velma comments how Simone walked down the tunnel and hadn't been dragged by a zombie. By then it was too late, though. Simone uses voodoo dolls to capture Fred, Daphne, Beau and Velma. As she ties up the dolls, the gang can't move in real life. Simone explains how to preserve her immortality, she has to drain the life force of victims she lures to the island. She and Lena turn into terrifying werecats. Meanwhile, Scooby and Shaggy run to the dock and meet up with Jacques who quickly turns into a werecat as well and begins to chase them.

Velma accuses Simone of stealing Morgan Moonscar's treasure. Simone yells in anger at the name of Moonscar and starts to detail the origin of the horrible curse: she explains how she was a peaceful settler until Morgan Moonscar drove all the islanders into the bayou and took over the island. She and Simone prayed to their cat god in order to destroy the pirates and receive immortality. The cat god granted their wish and turned them into werecats. They killed all the pirates and later plantation workers who had taken over the island. However, their wish came at a big price: upon becoming werecats, Simone and Lena were actually cursed into preserving their "immortality" at the expense of absorbing other people's souls every harvest moon, or else they will die. Jacques was also given immortality as a werecat.

As Simone is discussing her past, Scooby and Shaggy break into the voodoo room. She and Lena transform into stronger werecats and chase Scooby and Shaggy around the room. Velma reaches her voodoo doll with her feet and begins to untie her voodoo doll. Zombies enter the room as well and start chasing too. Daphne realizes the zombies are the "good guys" and warns Shaggy of Simone and Lena. The zombies help Shaggy and Scooby as Lena and Simone try to drain Shaggy and Scooby's life force. Daphne and Velma, now free, make voodoo dolls of Simone and Lena. They capture them temporarily. Beau waves a torch at them to keep them away.

Suddenly, the three werecats and the zombies start to shake and shrivel up into bones, then dust. Midnight had passed and the werecats had taken too long to drain life force. The eerie green light snakes throughout the room. The spirits of the zombies are avenged and can finally rest in peace.

Beau explains that he's really a detective, and had been investigating the disappearances on the island. After admiring the beautiful sunset, the gang drives onto the ferry and leave back for home. However, all of Simone's cats show up on the ferry as well (and oddly their eyes emit a sinister glow), much to Scooby's discomfort.

Continuity

 * In the flashback of the gang's old case, Fred and Daphne are wearing their original clothes based on 60s fashion, while in the present, they are now wearing more sophisticated and professional clothing.
 * Daphne's surname was revealed in The New Scooby and Scrappy Doo Show episode, No Sharking Zone.
 * Fred's surname was revealed in The New Scooby-Doo Mysteries episode, Happy Birthday, Scooby-Doo.
 * Velma's surname was revealed in The New Scooby-Doo Mysteries episode, Happy Birthday, Scooby-Doo.

Notes/trivia

 * The film was made as a result of testing well in a survey with mothers.
 * When it came time to devise the story, a "brain trust" came together, including Davis Doi, Jim Stenstrum, Glenn Leopold, and Lance Falk. The movie having a combination of fake and real monsters, was suggested by Falk to appease the differing views of Stenstrum, who wanted real monsters, and Leopold, who thought having real monsters was against the Scooby-Doo formula, as there needed to be a solvable mystery for the audience. Davis agreed to real monsters because he felt that the premise of having someone behind a fake monster couldn't hold for the length of a movie like it could for an episode.
 * This was supposed to be a one-off movie, so time was slightly more relaxed and had no studio interference.
 * The movie is based on Glenn Leopold's script for the unfinished SWAT Kats episode, The Curse of Kataluna. It was also partially reused for the The Real Adventures of Jonny Quest episode Eclipse, which incidentally, was set in New Orleans and had a young woman as the main villain called Elise Lenoir. If the aforementioned SWAT Kats episode had been made, then the story would've never been reused for this movie.
 * In a post-credits scene, Scooby feeds the cats some milk.
 * This movie features an all-new cast of voice actors for the adult Mystery Inc., save for Frank Welker who returns as Fred. This is the first Scooby-Doo production not to feature Don Messick and Casey Kasem as Scooby and Shaggy; Messick had passed away (with the film dedicated to him), while Kasem had protested Shaggy's carnivorous appetite as the actor was vegan, so Scott Innes and Billy West replaced them, respectively. From the next movie, Innes would voice both Scooby and Shaggy. Mary Kay Bergman and B.J. Ward replaced Heather North and Marla Frumkin as Daphne and Velma, respectively; Ward had previously voiced Velma in the Johnny Bravo episode, Bravo Dooby-Doo.
 * This is the first Scooby-Doo production that alludes to a romantic relationship between Fred and Daphne (which had been poked fun at in the Johnny Bravo episode, Bravo Dooby-Doo); they get jealous of each other when Fred takes a shine to Lena and Daphne is interested in Beau. Velma also forms a friendship with Beau but denies an attraction to him.
 * This is the only movie not executive produced by William Hanna and Joseph Barbera prior to their deaths, and the only movie that doesn't have the 'Special Thanks to Joe Ruby and Ken Spears' credit at the end, who were the creators of the characters. Instead, the former two are given sole credit for creating the characters when, in fact, it was just their company which produced it. In fact, Hanna himself said (via archive footage) on the Mystery Inc. Yearbook featurette (passed around a few of the DVDs in the early to mid-2000s) that it was a team effort. Later films would say "Based on Characters Created By Hanna-Barbera Productions".
 * The film ignores Scrappy-Doo, just focusing on the original core group.
 * The videos sold well and received generally positive reviews in the press, leading to a series of future direct-to-video feature films.
 * Out of all of the direct-to-video movies this one is arguably the darkest and most frightening out of all of them. The others were toned down at the request of the studio.
 * Also the only one where characters are killed: three on screen, dozens off.
 * It was nominated for an Annie in Outstanding Achievement in an Animated Home Video Production, and for an MPSE Golden Reel for sound editing for a direct-to-video, both in 1999.
 * This was the first time a real monster was discovered by the original Mystery Inc. gang.
 * While this was the movie's tagline, the original Mystery Inc. line-up did encounter real supernatural monsters and beings in the episodes Ghost Who's Coming to Dinner, Mystery in Persia, Ghosts of the Ancient Astronauts and A Halloween Hassle at Dracula's Castle.
 * Mr. Beeman's counterfeiting scheme is vaguely reminiscent of what Mr. Conrad did in the first A Pup Named Scooby-Doo episode,.
 * The house Daphne waits in front of (which presumably belongs to her), resembles the house Daphne and Velma shared together in the What's New, Scooby-Doo? episode A Scooby-Doo Valentine. Whether the latter was an intentional reference is unknown.
 * Daphne being the believer and Fred being sceptical is a reversal of A Pup Named Scooby-Doo, just without the cartoony exaggeration.
 * Notably, Fred is seen eating and drinking like a normal human being, probably more than he ever did in the almost thirty-year history of the series.
 * Snakebite may be a parody of "Crocodile" Dundee.
 * There are a few in-jokes as the gang settle into Moonscar Mansion, the first is when Shaggy ponders if he should dress up for dinner, opening a suitcase full of identical clothing he's already wearing, then he trims his whiskers, but they look no different; meanwhile Fred tries on an ascot before deciding against it.
 * When Fred is trying to "unmask" the zombie pirate he yells "It's the ferryman!" While Jacques is obviously not the zombie, he actually is one of the villains, and partly responsible for some of the events of the movie.
 * Morgan Moonscar can either be viewed as an anti-hero or as redeemed altogether. He was partly to blame for Simone and Lena's curse. In his undead form, he attempted to warn and/or help the living escape Simone and Lena.

Cultural references

 * Bubba Joe's is a parody of the Bubba Gump Shrimp Company, which was inspired by the film, Forrest Gump.
 * Simone was voiced by actress Adrienne Barbeau who is known for her roles as Catwoman in Batman: The Animated Series, and DJ Stevie Wayne in the 1980 horror film, The Fog, which deals with ghostly and/or undead sailors terrorizing a seaside town. Undead sailors (i.e. pirates) and cats are featured prominently in this film.
 * Simone appears to be similar to the vampire Count Dracula, winning the protagonists over with her mannerisms, lowering their guard before ultimately revealing her true nature and attacking them. The only difference being her temper.

Animation mistakes and/or technical glitches

 * When Pierre brings the guys their sandwich, the basket of peppers looks more like soup. The basket is also irregularly in front of the item next to it, instead of sitting next to it.
 * The Jacques Landing sign is missing grammar, so it neither says "Jacques' Landing" or "Jacques's Landing".
 * When Simone and Lena, as werecats, catch Scooby and Shaggy the first time, Scooby is missing his collar, which returns in the next shot, and later ripped off by Jacques. Scooby remains without a collar until the sunset, when they all leave Moonscar Island.
 * The glow on the cats' eyes aren't actually properly placed on their eyes, but above them.

Inconsistencies/continuity errors and/or goofs/oddities

 * Velma's bookshop has three different names: "Dinkley's Mystery Book Shoppe" on the window; "Dinkley's Mystery Books" on the sign sticking out; and then calls it "Mystery Inc. Bookshop" on the phone.
 * The Mystery Machine has been redesigned to be more like a mini van, yet in-universe, it's still supposed to be the same. Yet, in, Fred makes an oblique comment about it being good to be back in the old Mystery Machine, while riding around in the Cyber Gang's van.
 * Shaggy says to Scooby not to hog all the hot sauce, but he doesn't use any himself anyway.
 * It's unknown how Simone provided for herself and Lena, as well as pay Beau for his work. She could actually sell the island's peppers, but that would probably bring more attention to the island than she would want. Of course, she might have stolen money from the victims they drained, as if what they were doing wasn't bad enough.
 * When Fred recorded the zombies that are real and ran with Daphne, he held the VHS camcorder backwards, but in the next shot after that, he drops it forward in the quicksand.
 * Morgan Moonscar's buried treasure does exist, as shown in the flashback describing his demise. However, it is dropped from the story altogether as a red herring, but the treasure presumably is still there.
 * The flashbacks show his crew carrying the chest ashore and later beginning to bury it, so it appears that the motive of killing the colonists was (at least in part) to keep them from witnessing where he buried his treasure.
 * The chances of an undercover detective (especially one investigating a possible string of homicides) not carrying a gun or a dispatch radio are extremely remote, even in a cartoon.
 * How Simone and Lena got ahold of Velma's eye glass cleaning cloth and other articles of clothing and/or hair from Fred and Daphne was never explained. Beau already lived there so the two women could have taken something from him at anytime.
 * The reveal at the end of Simone's cats' eyes glowing could suggest something more to them, such as a long lifespan (even immortality), since they were more than just house pets, they were creatures that Simone and Lena worshipped in the 1700s, meaning the cats in the flashback and Simone's could be one in the same, although, of course, this isn't directly confirmed.
