Munchies

In "Munchies," space archaeologist Simon Watterman (Harvey Korman) discovers a creature in Peru that his evil twin brother Cecil kidnaps from him. The creature, Arnold, regenerates into multiple new creatures when chopped up and develops a taste for women, beer, and junk food. After some chaos and destruction, the main characters manage to defeat Arnold's minions and sell the creature's remains for $25,000.
