 While out in the woods, Cartman discovers a strange creature. Some government scientists tell the townspeople that the creature is a Jakovasaur: a prehistoric animal thought to be long extinct. Soon afterward, the first Jakovasaur s mate turns up in South Park, and the town immediately begins trying to get them to breed so their species can recover. This, however, leads to a bigger problem: the Jakovasaurs turn out to be so annoying that nobody (except for Cartman) can stand them.
