History WesternAnimation / ScoobyDooReturnToZombieIsland

First Trailer: [[https://www.youtube.com/watch?v=cgvO0vrHYrM Here]]

* ContinuitySnarl: Despite the retcon, Velma seems to forget Beau, the undercover cop/gardener, was likewise there during the whole events of the movies. Plus seems to forget that, despite her constantly stating the supernatural isn't real, that werecats used ''voodoo dolls'' on Fred, Daphne, Beau and her to subdue them so they could take their life energy more easily. They were nearly ''melted'' when the dolls were knocked near a torch. ''She herself'', along with Daphne, used the dolls against the werecats in the climax to stall them.

* StatusQuoIsGod: Technically, Even though ''WesternAnimation/ScoobyDooOnZombieIsland'' established that it took place in the Gang's adulthood after their teen sleuthing days in ''WesternAnimation/ScoobyDooWhereAreYou'', this movie instead {{retcon}}s it back to the Gang still being teenagers like in the original show and the other recent movies. Though it might be just a different continuity.

* AsYouKnow: Daphne recaps the original movie at one point to the entire gang, who, having experienced for themselves [[LampshadeHanging repeatedly remind her that they already know what happened]].

* CriticalResearchFailure: [[invoked]] Velma calls out Alan Smithee when one of his script points blatantly contradicts the actual report of Zombie Island. To which he reminds her his script is only "based on a true story".

* ContinuitySnarl: Despite the retcon, Velma seems to forget Bo, the undercover cop/gardener, was likewise there during the whole events of the movies. Plus seems to forget that, despite her constantly stating the supernatural isn't real, that werecats used ''voodoo dolls'' on Fred, Daphne, Bo and her to subdue them so they could take their life energy more easily. They were nearly ''melted'' when the dolls were knocked near a torch. ''She herself'', along with Daphne, used the dolls against the werecats in the climax to stall them.

* GreaterScopeVillain: [[spoiler:The reveal that the black werecat is real means that the unseen cat-god mentioned in passing in the original film becomes this for this film. We don't get any insight to the werecat's intentions or goals, but presumably it gained its' powers from being a follower of the same cat-god who turned Simone, Lena, and Jacques into the mass-murderers of the first film, who may or may not want revenge on the gang for defeating Simone's group...]]

* NiceJobBreakingItHero: Alan Smithee got the WHOLE idea for his movie due Velma maintaining a blog loaded with several that are still "unsolved" INCLUDING zombie island.

** The original movie was supposed to take place after the Gang's tenure as teen detective and in their adulthood, but this movie completely ignores it and states that they're still teenagers in high school.

** Weirdly enough, in the last movie Velma seemed pretty proud that the gang had no unsolved cases. Here she maintains a blog loaded with several that are still "unsolved", at least as far as she's concerned (Granted she probably meant with the whole gang together since Daphne, Shaggy and Scooby had several solo adventures) but it still pretty odd.
** In the original, Velma was the one who came up with a way to supernaturally defeat the antagonists by stalling them with voodoo dolls, she's also the one to explicitly say the zombies were real and their souls were finally put to rest. Here, she's the one to openly deny any supernatural activities that may have happened in the past.
* SequelHook: [[spoiler:While the three main "cat-monsters" were just villains in masks looking for Morgan Moonscar's missing treasure, the remaining one turns out to be a legitimate monster much like the ones from the first film... And likely will want to still seek revenge against the gang.]] What's more, after the main plot is resolved, special attention is givent o Scooby and Shaggy mentioning the potential of Alan making a trilogy, suggesting that a third ''Zombie Island'' film will one day be made, presumably [[spoiler:involving the true cat creature.]]

Though that might be just a different continuity.

* VileVillainSaccharineShow: While no way in comparison to the original film's villains, the real cat person or the cat god himself that appears throughout the movie is far more violent than any of the ScoobyDooHoax criminals in it. He even at one point sets fire to curtains inside the mansion.

* ContinuitySnarl: Despite the retcon, Velma seems to forget Bo, the undercover cop/gardener, was likewise there during the whole events of the movies. Plus seems to forget that, despite constantly stating supernatural isn't real, that werecats used ''voodoo dolls'' on Fred, Daphne, Bo and her to subdue them so they could take their life energy more easily. They were nearly ''melted'' when the dolls were knocked near a torch. ''She herself'', along with Daphne, used the dolls against the werecats in the climax to stall them.

* BroadStrokes: This film seems to be continuing on from where "Curse" left off with moving forward that the gang are still teenagers and the events such as Zombie Island took place in the past with the rounding off of problem elements into a new status quo. The original film, and the three films that followed it, heavily implied that the Gang were adults (due to them all having jobs, such as Velma having opened up her own bookstore, and Daphne having made her own talk show). This film ignores that aspect. While the end of "Curse of the 13th Ghost" had the gang talking about going back to mystery solving anyway it would appear that however much time passed between films they still hadn't done so yet.

* KarmaHoudini: [[spoiler: Alan Smithee just ups and walks away with Moonscar's treasure despite practically luring the gang in with a fake vacation for a dumb film and stranding the group and his actors there when he burns down the ferry to keep them from leaving despite being attacked by wild cats and (supposed) cat people. What's worse the gang just... let him do it without any complaints.]]

* BewaretheCuteOnes: When a harmless kitten comes out of the bushes, Scooby cowers as Shaggy said there was nothing to worry about. A few seconds later, the kitten roared like a tiger, shedding its cute facade.

* TheCameo: Elvira, yes ''[[Creator/ElviraMistressOfTheDark that Elvira]]'', shows up briefly with Shag and Scoob catching her show and she setting the plot into motion by declaring the two won a vacation and allowed to bring guests. [[spoiler: It's revealed later Alan contacted her to help fake the contest and lure the gang to the island for his plan.]]

* SequelHook: [[spoiler:While the three main "cat-monsters" were just villains in masks looking for Morgan Moonscar's missing treasure, the remaining one turns out to be a legitimate monster much like the ones from the first film... And likely will want to still seek revenge against the gang.]] What's more, after the main plot is resolved, special attention is given to the number three, and Scooby mentions the concept of trilogies, suggesting that a third ''Zombie Island'' film will one day be made, presumably [[spoiler:involving the true cat creature.]]
