Scooby-Doo! Return to Zombie Island is the thirtieth in a series of direct-to-video films based upon Hanna-Barbera's Scooby-Doo Saturday morning cartoons. It had its world premiere on July 21 at the San Diego Comic Con International 2019,[1] followed by Digital HD on September 3, and DVD on October 1.

It is a quasi sequel to Scooby-Doo on Zombie Island., the original direct-to-video film in the series. Notably, it was released during the 50th anniversary year of the Scooby-Doo franchise, making the film somewhat of an acknowledgement of that milestone, along with the previous DTV release, Scooby-Doo! and the Curse of the 13th Ghost.


The gang gets a tropical-themed vacation, which turns out to be on none other than Moonscar Island, where the gang run into more zombies and cat creatures. Could the gang have left the mystery unresolved all along? Velma seems to think so.

Soon, after cleaning the Mystery Machine, the gang capture more monsters, (including the Snow Ghost, the Creeper, and the Spooky Space Kook) who are the entire Withers family. But, as the gang congratulated themselves, the Mystery Machine went backwards, prompting Fred to give chase, but it turns out to have been a dream.

As Fred decides to come out of retirement after seeing a news report. Shaggy and Scooby refuse, saying that They've been taken For granted in all their mysteries, and has Fred, Daphne, and Velma promise never to solve another mystery. As the gang decide to have a vacation. They see a TV program featuring Elvira, who announces the winner of a tropical vacation, who is in fact, Shaggy Rogers, to the gang's confusion and Shaggy and Scooby's delight.

On the way to the island, via a ferry, Fred, Daphne, and Velma try to keep their promise, as Shaggy and Scooby relax. After arriving, two greeters frightfully tell the gang to "Get Out" but gets humorously ignored by the gang as they go in a van to the resort, with the two greeters saying "Tourists…" in a annoyed tone. On the way, a clawed figure slashes a palm tree causing it to block the road. forcing the gang to go to the resort by foot. As the van driver stays to repair His van. Arriving at Moonstar Island Resort, which reminded the gang of Moonscar Island, involving the zombies and Cat Creatures. Coming inside the resort, they meet the Hotel Manager, Alan. And the hotel staff, composed of Mona, Linda, Jack and Bugbite Stubbs, who resemble the people the gang encountered. While enjoying the accommodations, a few zombies surprise Scooby and Shaggy who make a run for it and hide in a cabinet, which leads to a cavern, complete with cat statues and monuments.

Soon, Shaggy and Scooby return to the hotel and barricade the door, as a group of zombies approach the hotel. Shaggy and Scooby give their OK to the others to solve mysteries again, the gang set a trap for the zombies to be caught in. But, the black Were-Cat knocks over a candelabra setting fire to a curtain, which the fire's smoke causes the sprinkler system to douse the fire and melt the zombies' faces, but as it turns out, the zombies were the hotel staff, and That they're really on Moonscar Island which is also a filming location! Alan confesses to the gang that He's a film director, known as Alan Smithee, who wanted to make a scary movie after looking into Velma's unsolved mysteries blog. He also revealed that He sponsored the vacation for Shaggy to win. Of course, Alan had no knowledge of the black werecat. Despite everything that happened, the gang offered to help Alan finish the movie. During the recontinued filming, the gang meet Seaver, a stunt double for Fred, who also shows a monster truck version of the Mystery Machine. then, as the sun was going down, Velma go into the forest wearing night-vision goggles see a clowder of cats' eyes, and runs for it.

After Velma tells the others to make a run for their lives, they see a harmless-looking beige kitten coming out of the bushes out, startling Scooby and a few seconds after Shaggy said there's nothing to worry about, the kitten (fully grown in an instant) turns feral and roared like a tiger, scaring Shaggy as more cats attack. After the movie crew (except Alan and Seaver) hide, three were-cats appear. As the Gang and Seaver run for the ferry, Alan crazily burns it. But, Fred on impulse, rescues the Mystery Machine from being burned with the Ferry.

Soon, they are attacked by the gang which resemble zombies, scaring the cat creatures in a hole. The gang unmasked the creatures which were in fact, The greeters and the ship captain.

  • The first malt shop waitress's model is reused from Faith's from the DTV Scooby-Doo! Legend of the Phantosaur.
  • The film Elvira was going to show after announcing the vacation winner, was called Predator Jones.
  • Though Scooby-Doo on Zombie Island. was produced using traditional hand-drawn animation, the flashbacks seen in Scooby-Doo! Return to Zombie Island were recreated using computer animation to resemble the original sequences.

Cultural references

  • Cassandra Peterson/Elvira hosts a similar program as she does in the real-world. Peterson also played a similar parody of herself called Drella Diabolique in the DTV LEGO Scooby-Doo! Haunted Hollywood.
  • The director's name, "Allan Smithee," is an inside joke to Hollywood directors who use that pseudonym to disavow their work/association with it.


Animation mistakes and/or technical glitches

  • During the intro, when Jacques was chasing Mystery Inc, his tail was missing.
  • In one of the flashback scenes, the Mystery Machine is not the news van that was used in the original.
  • While Alan was videotaping the cats attacking the crew, the cat before attacking him was brown, but was gray when doing it.
  • When the police comes to arrest the culprits, the female culprit's cat-hands/gloves are missing, showing her regular hands. But the very next scene shows her being handcuffed WITH the gloves on.
  • When the six cats enter the cavern, there were two orange cats, but not a brown one to be seen until the cats were gathering at the spot where Moonscar's treasure is buried. But, in the next scene, the Black cat switched places with the blueish one. Then, after Velma explained that the Cats were guardians of Moonscar's treasure, the Black, Blue, and Gray Cats were in different spots.
  • At the final scene where Scooby victoriously eat Scooby Snacks, the orange cat who was nuzzling Shaggy's knee in the previous scene, traded places with a blueish cat, who is sleeping.

Inconsistencies/continuity errors and/or goofs/oddities

  • In Fred's dream of the "good old days," he and the gang are much more menacing than they are in real life. Not only do they seem to get a perverse pleasure out of chasing down bad guys, but some of the culprits look like they actually fear the gang.
  • The ending of the previous DTV release strongly implied that the gang would go back and regain their reputation to prove the Sheriff wrong, all of which is ignored in this film.
  • The Sheriff says they should treat themselves to a vacation, which they do almost 100% of the time anyway.
  • It's unknown if Elvira knew the anonymous sponsor and was keeping it hidden to her audience, or her show actually accepts and provides vacations from people without making a background check on them.
    • It's never revealed what type of contest Shaggy was supposed to have entered, nor does he show any memory of having entered one. It seems like it's just comes up out of the blue. The gang are also surprised by being brought back to Moonscar Island/Moonscar Mansion, as if they were given no previous insight to where they were heading. They just put their lives in the hands of some contest they just happened to see on TV.
  • In Scooby-Doo on Zombie Island, Simone Lenoir's mansion wasn't a hotel open to the public, therefore didn't require a guestbook, but this film dictates the opposite, and that Alan Smithee reused it at Moonstar Island Resort, just with the pages having been ripped out, to further fool the gang into thinking they're not at the same mansion.
  • Flashbacks are shown of the gang's previous time on the island, but Velma regularly rants about not believing everything she saw and attributes the experience to hallucinations brought on by swamp gas. Moreover, this would mean that what they faced previously resulted in an unresolved/unsolved mystery. While she acted similarly in Curse of the 13th Ghost, Velma's defiant ignorance is somewhat justified in that context as she did not witness the events that led to the hunt for the 13th Ghost. In this case, though, Velma was originally a witness to the events and this movie relies on flashbacks of Scooby-Doo on Zombie Island.. This makes her appear overly irrational just for the sake of not wanting to face the facts of what really happened, which could've been used as character development in acceptance.
  • During the flashback, Morgan Moonscar never had a scar around his left eye, and when the Were-Cats died, they disintegrated into green dust instead of gray dust.
  • Because the gang have regressed from adults back to teenagers over the course of other direct-to-video releases since Scooby-Doo on Zombie Island, several plot elements in the original film must be retconned, including some fairly unconvincing changes. For example, Daphne being the host of her own show is changed to her being on a school project, which for some reason gained interest from Chris, the talk show host.
  • There was a real black cat person among the fake ones which was left a mystery, as if to leave it open ended for the audience to make up their own minds if the cat people are real or not. However, it was clearly established in the original film that the cat people were real, thus making the addition of a mystery cat person both redundant and somewhat out of step with the prior film's events.
  • Beau Neville does not appear in flashbacks or have an actor counterpart, making him the only character from the original movie not to be in this movie in some way.
  • This is a quasi sequel to Scooby-Doo! and the Curse of the 13th Ghost too (the Sheriff storyline), yet Velma and Fred said the 13 ghost case was their first "real monsters" case, and here the gang remembers the events of Scooby-Doo on Zombie Island. (which had real monsters).
