Created by Joe Murray, the series takes place in and around O-Town, following the surreal and often parodic adventures of Rocko, an anthropomorphic wallaby who has immigrated to O-Town from Australia. The show also showcases his friends: Heffer, the gluttonous cattle; Filburt, the neurotic turtle; and Rocko's dog, Spunky. Despite being primarily a children's show, it is laden with adult humor, including double entendres, innuendos, and satirical social commentary.
