Rat Fink

Ed Roth's most famous invention, Rat Fink is a repulsive green rat with lumpy skin, shriveled eyes, and humanoid feet, commonly associated with the hot-rod scene of the 1950s and 1960s.
According to the documentary "Tales of Rat Fink", Ed Roth was thinking about how much he hated Mickey Mouse when he sketched Rat Fink.
