History Fridge / ScoobyDooOnZombieIsland

* The four hoaxes busted by the gang during "The Ghost Is Here" offer a perfect selection of classic ScoobyDooHoax themes: the seance-ghost fits the "creepy occultist with prop gadgets", the man-bat/vampire fits the "cartoon take on Film/HammerHorror monster" (complete with Shaggy trying to repel it with a mirror), the riverboat spook plays off the old shows' frequent "notorious local historical character's ghost" motif and the lobster-thing embodies the "monster spawned of whatever-the-factory-the-crook's-robbing-happens-to-manufacture" premise that's virtually unique to the franchise.

* Seeing that among the zombies are Confederate soldiers from the Civil War indicates that the villains slaughtered [[OneManArmy an entire regiment of soldiers]] at least once, and the soldiers most likely tried to put up a fight for all the good it did them. That raises the hideous implication that the werecats may well have been powerful enough due to the curse that bullets and bayonets had little to no effect on them. What's more is that they almost certainly did so without the Confederate or Union governments being any the wiser, the chaos of the war a perfect cover for Simone and Lena's killing spree. It's also possible that the Union soldiers seen as zombies at one point were sent in search of the unaccounted-for 8th Alabama at the end of the war, only to join their erstwhile foes as undead.

** When Simone, Lena, and Jascue's goals are boiled down, it's essentially a murder scam operation where they lure in unsuspecting victims luring them into a false sense of security before they inevitably have to run to their protection from the monsters that suddenly appear, only for them to be victims of the real monsters that drain their life force and add them to the countless victims they have added- with the added irony being the "monsters" also being victims that try to unsuccessful warn them of their real monsters. They're essentially SerialKillers mixed with natural predators that trap their victims to feed them, and demons that subject their victims to unjustified torment just to prolong their lives and out of sadism.

** There's the fact that the zombies are dressed in drastically different time periods, from 18th-century pirates, Civil War confederates, 30s mafia members, and even local tourists of implied present day. The usual VillainOfTheWeek sticks to one theme for their respective monster of their local area. If it were just the pirates, it would make sense they'd be a collection of disguises that would be somewhat difficult to solve normally- which is initially implied to be a front for Simoe and co.'s suspicious activities, but the time period clashes of the zombies would be too complicated to make a feasible story for criminals to hide behind. The simpler and rational yet irrational explanation is that they're indeed real- being victims across different time periods and something or someone made them this way in the first place for truly nefarious reasons. And since it becomes gradually obvious the undercover detective isn't behind it, it's obvious the current owners of the plantation are behind it.
* The zombies disappear from the film after the Terror Time montage, since the gang all end up back at the plantation mansion. This isn't the filmmakers being lazy, either Simone and Lena put some kind of magic ward to keep them out or, much more likely, the zombies are either actively avoiding going anywhere near the Werecats. After all, it's not like they can do anything to stop them.

* It's unlikely that the gang is the only one the zombies appeared to. Unlike the gang, who'd seen their fair share of {{Scooby Doo Hoax}}es and became cynical of real monsters, the previous visitors ''wouldn't'' dismiss these zombies as fakes and realize they're real. Imagine being a tourist and going to a bayou island for a nice vacation, everything seems fine, the hosts are lovely and friendly, then ZOMBIES ATTACK and you're left defenseless as the undead keep coming after you. You want to leave, but you ''can't.'' You can only hope the ferry comes back before you die. Then the ferry comes...and the captain turns out to be a cat monster who wants to drain you of your life force until you're a shriveled husk. Since the hosts were so nice to you, you decide to warn them that Jacques is secretly an evil cat monster. But as it turns out, they're also cat monsters who proceed to drain you alive. Even in death, you can't find peace and your only recourse is to join the zombies and try to warn the next batch of visitors about the women and the ferry driver and hope they don't make the same mistake as you did.

* Lena claims that the tunnel under the mansion was dug "to hide from Union soldiers." We later learn this is not the case. But even before this, there's a few clues suggesting she's lying, if the island's history is any indication. It's so remote that it's difficult to get to even in modern times and is in a bayou that few people enter for any reason, so the chances of the islanders being visited by the Union Army with any regularity are slim. Note, too, there are fewer Union soldier zombies than Confederate ones, further supporting the notion that Northern troops rarely came there. From this, it can be gleaned that the tunnel was ''not'' dug for the purpose Lena claims.

* When Scooby and Shaggy have unwittingly entered Simone's chamber and find the dolls of Daphne, Velma and Fred, the bats swarm out. This is a nice Scooby gag of having bats come out of nowhere just to give them a scare. But, looking at what happens later, it doesn't take long for a savvy viewer to realize that the bats' behavior was triggered not by Scooby and Shaggy, but by Simone entering the chamber with Beau's voodoo doll, as it was not there when Shaggy and Scooby first played with them. Simone likely triggered the bats intentionally to get Scooby and Shaggy away from the dolls without revealing herself and her true evil nature to them, and by extension to the audience.

** Even worse, Shaggy and Scooby dip into those waters by accident with a mouthful, and Snakebite Scruggs regularly ''fishes'' from them, all of them completely unaware of how filled to the brim with buried and decomposed corpses the bayou is. NauseaFuel at its finest.

** On that note, its possible that on some level, the lyrics for "Terror Time Again" are from the ''zombies'' point of view as they see that it's time for another sacrifice and once again they aren't having any luck and have to deal with knowing that's to come.

* Simone stating that it was necessary for Lena to lure outsiders to Moonscar Island. Since several victims are from time periods where there was no quick travel meant Lena had to plan out when people would come to the island.
* Simone stating that she has been killing people for 200 years. Given the implication of just how large some of the groups who were her victims, its implied her body count could run into potentially thousands of people dead.

* While the era of the 1700's and the Civil War and tropical disease, not to mention the threat of a ship getting lost at sea would be able to explain away most of the disappearances, the modern era victims would not have that luck. As a result, since many of them look like modern tourists, it doesn't take a lot of imagination for some of these poor people to have told their kids that they would be away for a few days and then they get brutally murdered, never to return home.

*** Alternatively, it could be because the bodies were dumped in the swamp, bodies dumped in sources of water have been known to bloat up.

* The way Simone and Lena talk about how they cursed themselves makes it likely that they were forced to start killing others to stay alive from the very start after Moonscar. It's very much a possibility that they weren't originally so untroubled and sadistic about it, but were just desperate and afraid to die before their time, but as the years went by, found out that MurderMakesYouCrazy and either decided to keep from dying ''ever''.

* The fact that Beau is specifically noted as being the estates new gardener and how they had a doll ready for him indicates that other past victims had been servants who Simone and Lena had hired. Those people would have likely had it especially bad, being betrayed and murdered like that by people they'd come to know and trust over a long time period.
* Not only is the zombie body count excessive, but keep in mind how the spectral nature of the zombie curse seems to work, reanimating flesh on top of decayed remains and bone. With how many of the zombies rise from the bayou waters, it's entirely plausible that a very uncomfortable amount of those waters are filled with long-rotted and decayed corpses, and potentially no way to even find or recognize them anymore until the curse brings them back temporarily, and ''no way to leave'' without Jaque's boat. The perfect territory for a SerialKiller trio and no way to even find evidence of it at all.
