->''"And now, ladies and gentlemen, we remind you to take heed and be cautious, for there are things out there…"''
-->--'''Intro for “Things Out There”'''

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

The first one is ''Alvin and the Chipmunks Meet Frankenstein'', a horror-themed animated film that came out in 1999 produced by [[Creator/{{Universal}} Universal Animation Studios]], animated by Creator/TamaProductions, and distributed by Universal Studios Home Entertainment.

While the Chipmunks are working in a famous movie studio park called Majestic Studios in a singing attraction, the real Dr. Frankenstein comes to work in the studio's most famous attraction, Frankenstein's Castle. After Alvin drives a crazy bus chase, they miss their next performance and get locked in the studio after closing time. Dr. Frankenstein figures the castle is not scary enough so he re-builds the real Frankenstein. IT COMES ALIVE! So it finds the boys and starts a wild and scary adventure!

!!Tropes:

* ActorAllusion: This is the second time Michael Bell has played a character who built a humanoid being: The first one was Clockwork Smurf as [[WesternAnimation/TheSmurfs1981 Handy Smurf]].
* AdaptationalVillainy: Victor Frankenstein is portrayed as a CardCarryingVillain who abducts Alvin to change him into a monster when he is upset by the original monster's GentleGiant nature, and at one point threatens to ''eat'' people.
* AlternateIdentityAmnesia: Alvin has little-to-no recollection of his actions as a mutant {{Toon}}.
* BrainInAJar: Dr. Frankenstein has a collection of live brains in jars which he displays in his laboratory.
* BringIt: "If A Monster Came In Your Room" is the Chipmunks singing about how they'd fight off and defeat any monster who dared enter their room, encouraging even Theodore to take confidence in himself.
* BigNo: Alvin screams this as Dr. Frankenstein feeds him the frappe.
* ContrivedCoincidence: What are the odds that the ingredients of the antidote were found at a buffet table?
* CurseEscapeClause: The Cartoon Monster Maker Frappe can be undone by a special antidote made out of the buffet food from the premiere; however, the victim must be upside down for it to work.
* DeliberatelyMonochrome: The prologue is entirely in black and white as an homage to classic horror films.
* DenserAndWackier: There's more slapstick, and goofy humor in this movie than in previous Alvin and the Chipmunk incarnations.
* DrFrankenstein: Dr Frankenstein is depicted here as an outright CardCarryingVillain in pursuit of his monster who is depicted here as a GentleGiant. He later tries to turn Alvin himself into his next experiment.
* EarWorm: The Sammy Squirrel theme song. Even Dr. Frankenstein, who hates the character and song, can't stop humming it to himself at one point, exclaiming "I can't get that song out of my head!"
* ExtremelyShortTimespan: The movie is set over a period of three days.
* FamilyUnfriendlyDeath: The Chipmunks bury an imaginary FrankensteinsMonster alive while singing "Will make this place his tomb!" during their "''What If a Monster Came into Our Room''" song. [[spoiler:This is before they realized the FrankensteinsMonster that was chasing them happened to be a {{gentle giant}}.]]
* FrankensteinsMonster: Obviously, the Frankenstein monster appears in the film.
* GentleGiant: Frankenstein's monster proves to actually be good-natured and not a bad person.
* GoryDiscretionShot: Victor removes the monster’s head in the prologue and drops him, and the splattering sound effect suggests it wasn’t a pretty sight to behold, though it only happens offscreen. None of the monster’s body parts are ever shown before the monster is fully reassembled either.
* HoistByHisOwnPetard: Victor plans to shock Alvin back into his cartoon monster form onstage at the Chipmunks show by bombarding his microphone with a large amount of electricity; however, Frankie hears of his plans and tricks Victor into touching the mic instead.
* HypocriticalHumor: The blonde woman who is Billy’s mother at first lambasts the actor who fumbled his role as Frankenstein’s monster due to not scaring Billy. However, when Alvin successfully scares Billy by accident later, she rips into him for doing so.
* ImAHumanitarian: Early on, Victor threatens to turn the park visitors into lunch meat unless they scram. It’s never clarified if he just means he’s going to tear them apart… or ''eat'' them.
* InflatingBodyGag: Alvin undergoes this as the "Cartoon Monster Maker Frappe" starts to take its full effect on him.
* LaserGuidedKarma: Dr. Frankenstein hates Sammy Squirrel. His comeuppance is getting stuck in a Sammy Squirrel suit and being forced to play the character at the park.
* ThisIsNoTimeForKnitting: Simon finds the recipe for an antidote to cure Alvin in Dr. Frankenstein's book, but the instructions are in SesquipedalianLoquaciousness. Theodore then goes to load a plate at the buffet table and reveals that the ingredients can be found among the buffet spread.
* MadScientistLaboratory: Dr. Frankenstein has a lab in a castle... at an amusement park no less!
* MockyMouse: Being a cartoon rodent with an AlliterativeName and a SpeciesSurname in addition to being a theme park mascot (albeit one for a theme park based more on Universal Studios Hollywood than Disneyland), Sammy Squirrel is a clear stand-in for Mickey Mouse.
* MusicalWorldHypothesis: The three songs in the film follow this order: Diegetic, Alternate Universe, All In Their Heads.
* MythologyGag: When the Chipmunks' faces are distorted by fear and g-forces in the runaway roller coaster, they are for a brief moment turn to how they appeared in ''WesternAnimation/TheAlvinShow'', then to "realistic" looking chipmunks as on their first album covers before returning to their normal selves.
* ObviouslyEvil: Victor is a poor-tempered old crook who frequently threatens people and not so subtly eyes them for potential body part donations. Yesman seems to recognize this, but he’s so afraid of the park failing that he stays out of his way.
* OhCrap: Simon when he realizes three minutes have passed since Alvin was given Cartoon Monster Maker Frappe, causing it to take its full effect.
* PapaWolf: When Mr. Yesman threatens to blacklist the boys after learning they haven't showed up to the premiere, Dave [[TranquilFury calmly, yet defiantly]] defends the boys, saying that [[TemptingFate "they're not monsters"]].
* ProductionForeshadowing: In “Things Out There”, the song mentions the Wolfman as one of the monsters that you could meet in the night, foreshadowing the main threat of the next film.
* PunctuatedForEmphasis: "Don't. Touch. The cap."
* RefugeInAudacity: This is how Victor wards off the angry mob during the prologue, describing exactly how he brought his creation to life before demanding them to think about how ridiculous it sounds. The villagers fold and leave in a huff.
* RoundaboutShot: One of these occurs during the "If You Wanna Have Friends" montage as the Chipmunks and the children dance around Frankie.
* ShockAndAwe:
** The Cartoon Monster Maker Frappe that the doctor gives Alvin includes shocking him with 50,000 volt chaser following the ingestion, which will cause it to take its full effect within three minutes after the shocking.
** The doctor tries to get this to happen to Alvin again by rigging his microphone with high voltage, given that the frappe hasn't completely been digested yet. However, Frankie finds out and tricks the doctor into getting shocked himself instead.
* ShoutOut: See the main [[ShoutOut/AlvinAndTheChipmunks shout out page]] for the franchise.
* {{Toon}}: What Dr. Frankenstein managed to turn Alvin into when trying to turn him into a monster, a little cartoon troublemaker.
* VocalDissonance: At first, Frankie's only able to utter deep, moaning noises. By the time he [[SuddenlySpeaking learns to speak properly]], he talks in a high-pitched, squeaky voice just like the Chipmunks. Must have something to do with the fact the Chipmunks themselves taught him how to speak.
* WingdingEyes: Alvin has a spiral for one eye when turned into a cartoon mutant.
