History WesternAnimation / AlvinAndTheChipmunksMeetTheWolfman

** [[Spoiler:The Wolfman himself]] has this reaction when [[spoiler:he sees that Dave armed himself with the silver head of the cane]].

* LockedOutOfTheLoop: Dave is never informed that Theodore [[spoiler:got turned into a werewolf]].

* DefeatMeansRespect: After dodging one of Nathan's pranks, Nathan's prank backfires on him and he even admits it was pretty cool after Theodore helps him up. Nathan is even seen dancing with the other kids at the DancePartyEnding.

* PapaWolf: [[spoiler:When Dave sees that Talbot is the Wolfman, the first thing that comes to his mind is to rush to the school and warn the kids. He also makes it clear that he is going to ''kill'' the Wolfman to keep his boys safe, if it weren't for the fact Talbot has already been cured when he finally gets to the school.]]

* SympathyForTheDevil: Jeanette states she feels bad for Nathan, theorizing his bullying is a result of being in an abusive family.

* ArtisticLicenseBiology: The doctor's statement that Theodore is more prone to exhibiting werewolf behavior than a human would be due to already being closer to a "primitive animal state" is rather fallacious when you consider that rodents, such as chipmunks, are actually more closely related to primates, such as humans, than they are to carnivorans like wolves. [[note]] Primates and rodents both belong to the superorder Euarchontoglires, while carnivorans are part of the sister clade Laurasiatheria. [[/note]]

* ArtisticLicenseBiology: The doctor’s statement that Theodore is more prone to exhibiting werewolf behavior than a human would be due to already being closer to a “primitive animal state” is rather fallacious when you consider that rodents, such as chipmunks, are actually more closely related to primates, such as humans, than they are to carnivorans like wolves.

* GutturalGrowler: Mr. Talbot speaks like this.

* ForWantOfANail: Had Alvin not tossed the necklace out the window, Theodore wouldn't have given it to Eleanor and leading into two important plot points: [[spoiler: 1) that Theodore became a werewolf and 2) same necklace saves Eleanor from Theodore when he becomes a complete werewolf.]]

* AllPartOfTheShow: When the Dr. Jekyll and Mr. Hyde school play begins and then it is continually interrupted by [[spoiler: Talbot and Theodore becoming werewolves]]. Although frightened, nobody in the audience watching intervene because they think it is all part of the show and applaud and that it is just good acting and stage makeup. Alvin has to be the one to inform Eleanor that it is not make-up; [[spoiler: Theodore is a werewolf]].

* BlessedWithSuck: [[spoiler: Theodore becomes a werewolf. His werewolf physicality means he is much more athletic and he is able to become a much better actor to portray Mr. Hyde in the school's play. But not only does his personality change and give him a bad attitude, during the full moon he turns into a monster overcome with canine instinct.]]

* InvoluntaryShapeshifter: [[spoiler:Dave finds out the hard way...]]

* BareYourMidriff: During the Jekyll-Hyde wrap party, Eleanor wears a party outfit that exposes her stomach. It's a wonder she weren't reprimanded for possibly violating any school dress codes. Brittany also wears something similar midway through the movie.

* AlternateIdentityAmnesia: [[spoiler:Theodore has no recollection of being a werewolf upon being cured.]]

* KnightOfCerebus: [[spoiler:Unlike FrankensteinsMonster in [[WesternAnimation/AlvinAndTheChipmunksMeetFrankenstein the previous crossover film with]] Franchise/UniversalHorror, the WolfMan is played completely seriously, being a being of pure predatory instinct as in the original source.]]

** Brittany faints when she encounters [[spoiler:the Wolfman]].

* AdultFear: Chipmunk or not, there is the idea of your son going out alone at night and getting attacked and bitten by a large dog. It's a good thing Theodore didn't contract Rabies, though [[spoiler:what he actually got is arguably ''worse'']].
