Alvin and the Chipmunks Meet Frankenstein

The Chipmunks perform at a theme park called Majestic Movie Studios. While taking a break from their concert, they get lost and are locked in the park after closing time. A real Dr. Frankenstein creates a monster for an attraction called "Frankenstein's Castle," which becomes the monster's companion, Frankie, when it befriends Theodore's teddy bear. The Chipmunks teach Frankie to be nicer, and Dr. Frankenstein kidnaps Alvin to force-feed him a potion, transforming him into a zany cartoon monster that must be stopped with an antidote mixture made from food items.
