History WesternAnimation / ScoobyDooReturnToZombieIsland

* LighterAndSofter: The film is much lighter than the first ''Zombie Island'' film. Most notably [[spoiler:nobody dies in this one.]]

* ArtShiftedSequel: The film uses the same style and [[Creator/DIgitalEMation animation studio]] as seen in the recent movies instead of the more {{Animesque}} style used by Creator/MookDLE in the original. Flashbacks to the events of the original are also redone in the modern style.

* AdaptationalModesty: Though still fairly attractive , Elvira wears a less revealing outfit, particularly in how there's much less cleavage being exposed.

* CriticalResearchFailure: 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".

* ThatOneCase: As a part of Velma's current character we learn she refers the events of cases with actual supernatural elements like of ''Scooby-Doo on Zombie Island'' as "the unsolved capers" and maintains a section of them on her blog.

** In the original, Velma was the one who theorized the zombies were all good people and the curse was real. Here, she's the one to openly deny it.

* 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.

Having solved mysteries all over Mississippi, Mystery Inc. has come to a surprising revelation - they have no more mysteries to solve! Thus, the best thing to do is to take a vacation. However, their vacation spot is one they didn't expect to return to - Moonscar Island, the site of their first encounter with real monsters. Even worse, the zombies that infested the island have returned. Now, Mystery Inc. needs to fully solve this haunting caper if they ever want to get back to the mainland alive and in one piece.

This film ignores that aspect.

** 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 she is concerned.

* StatusQuoIsGod:
** 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.

* AdaptationalModesty: Though still fairly attentive, Elvira wears a less revealing outfit, particularly in how there's much less cleavage being exposed.

* ArtShiftedSequel: The film uses the same style and [[Creator/DIgitalEMation animation studio]] as seen in the recent movies instead of the more {{Animesque}} style used by Creator/MookDLE in the original.
* BroadStrokes: 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, and features Mystery Inc. as teenagers.

* CoolCar: In the first trailer, the Mystery Machine is shown getting a set of monster truck tires, getting renamed "The Monster Machine".
* GetOut: In the first trailer, upon arriving on Moonscar Island, the gang is immediately told "Get... ouuuuut..." by one of the welcoming hosts.

* 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...]]

* ThatOneCase: In the first trailer, Velma refers the events of ''Scooby-Doo on Zombie Island'' as the "Zombie Island Mystery", "one of the unsolved capers".

** Despite ''WesternAnimation/ScoobyDooAndTheCurseOfThe13thGhost'' forcing Mystery Inc into early retirement and having the Mystery Machine sold off, they are back in business here and with their trademark van ([[ReplacementGoldfish kind of]]).

[[caption-width-right:350:It's terror time... again.]]

* MythologyGag: Velma mentions that besides the Zombie Island case, another case that went unsolved was the Reluctant Werewolf case...

* ContinuityPorn: LOTS, from featuring some of the classic 'WesternAnimation/ScoobyDooWhereAreYou'' monsters in the opening dream sequence, to recalling the events early on in ''WesternAnimation/ScoobyDooAndTheCurseOfThe13thGhost'' (including the Mystery Machine being sold, much to Fred's chagrin.)
