hile 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.
