Between 1999 and 2005, Bagdasarian Productions released three [[DirectToVideo direct-to-videos]] based on the '80s ''WesternAnimation/AlvinAndTheChipmunks'' series.

The second one came out in 2000, an animated horror-themed film entitled '''''Alvin and the Chipmunks Meet the Wolfman'''''. Like the previous direct-to-video, it was produced by [[Creator/{{Universal}} Universal Animation Studios]], animated by Creator/TamaProductions, and distributed by Universal Studios Home Entertainment.

Alvin thinks of himself as an expert on spooky stuff such as vampires and werewolfs, so when a mysterious stranger moves in next door, Alvin's convinced he's a werewolf. Then, when Theodore gets bitten by a "dog", he starts chewing socks, eating meaty stuff, and is a lot faster, even Simon thinks something's not right. But at the moment, he's more like a werepuppy. They now have to find a way to cure him before the next full moon, during the school play, ''Dr. Jekyll and Mr. Hyde'', or else Theodore will become a werewolf forever!

!!''Alvin and the Chipmunks Meet the Wolfman'' provides examples of the following tropes:

* AntiHero: The Wolfe-fied version of [[spoiler:Theodore plays as a [[NominalHero Type V]].]]
* AscendedExtra: Eleanor is a variation of this. She was often overshadowed and underused throughout the franchise, particularly [[WesternAnimation/AlvinAndTheChipmunks the '80s cartoon series]], though in this movie, considering that much of the plot focuses on Theodore, being his [[DistaffCounterpart counterpart]], she gets quite a bit of exposure.
* AsideGlance: Alvin gives a quick one after Simon explains the DeusExMachina way Theodore is cured.
* BareYourMidriff / DangerouslyShortSkirt: Eleanor and Jeanette, of all characters. During the Jekyll-Hyde wrap party, Eleanor wears a skimpy little outfit that exposes her navel, while Jeanette wears an incredibly short dress that comes down to her upper thighs... it's a wonder they weren't reprimanded for possibly violating any school dresscodes.
* BigDamnHeroes: [[spoiler:Despite Theodore's transformation, he manages to retain enough of his senses to fight off Talbot!Wolfman in order to protect Eleanor from the older Wolfman.]]
* DamselInDistress: Eleanor near the end of the film.
* InvoluntaryShapeshifter: [[spoiler:Dave finds out the hard way...]]
* IveGotAnXAndImNotAfraidToUseIt: "I've got a lemon zester and I'm not afraid to use it!" Said by the Chipmunks' neighbor when Simon and Alvin accidentally wake him up, while they go after werewolf-transformed Theodore as he escapes the house and they try to get him back.
* MagicPants: [[spoiler:Both Theodore and Mr. Talbot.]]
* LegacyCharacter: It's implied that Mr. Talbot [[spoiler:is a descendant of Lawrence Stewart "Larry" Talbot, the main character of Universal's original series of ''[[Film/TheWolfMan1941 Wolf Man]]'' films.]]
* OminousFog: Brittany even comments on how much she dislikes the particular kind of weather at one point.
* OurWerewolvesAreDifferent: [[spoiler:Theodore as a [[{{Pun}} weremunk]]]].
* {{Shapeshifting}}
* SharpDressedMan: The Chipmunks' new neighbor, [[NameDrop Mr. Talbot]].
* ShoutOut: See the main [[ShoutOut/AlvinAndTheChipmunks shout out page]] for the franchise.
* ThrowItIn: In-universe, the play goes off the rails when [[spoiler:Theodore transforms]] and the kids are forced to improvise, such as Simon and Janet acting out a scene where Jekyll has apparently split into three people, include a girl copy. During the after party, the director takes credit for everything the kids made up, though Principal Milliken just responds to everything he says with a dismissive "Uh-huh."
* TookALevelInJerkass: It may be because she gets limited scenes, therefore not much of her character traits are shown, but Brittany is noticeably brattier than usual.
* TransformationSequence: Simon has the honor being front-row center for [[spoiler:Theodore]]'s transformation.
* TrailersAlwaysSpoil: Also counts as a Covers Always Spoil as well since both show [[spoiler:Theodore as a werewolf.]]
* WolfMan
* YoungerThanTheyLook: Principal Milliken is only 31, but looks 50, due to the stress of dealing with Alvin for so long.
