Cartman finds a strange, yet annoying, creature in the woods. The boys get Jimbo and Ned to capture it, and they show it to the rest of South Park. It is determined that it is a Jakovasaur -- a species long thought to be extinct. The creature's mate arrives and Mephesto helps them reproduce, creating a multitude of little, annoying, loud creatures. Everybody in South Park, except Cartman, despises the creatures and go to various lengths to get rid of them.
