In Reptilicus. Copenhagen is terrorized by a prehistoric beast that has regenerated itself from a recently discovered tail segment. In the host segments, Gizmonic's crack space pilot Jonah Heston is lured to Moon Base 13 where he is the subject in a series of experiments created by Kinga Forrester to break his spirit by showing him cheesy movies. Only by riffing on the bad movies with the help of his new robot friends Tom Servo and Crow T. Robot can Jonah keep his sanity.
