While investigating the disappearance of a park statue, Chip and Dale are kidnapped by Moose and Rocco, two goons of Ratso Ratskiwatski, the infamous gangster. Ratso's daughter, Buffy, a mean looking eight year old girl, wants two squirrels as pets to play with, and terrorizes Chip and Dale in her doll house, sports car and electric train. Meanwhile, after the disappearance of the Art Museum, Gadget, Monty and Zipper follow the clues to Ratso's mansion, where they discover Ratso has stolen Professor Nimnul and his giganto gun, using it in reverse to shrink the statue and museum.
