Rocko's Modern Life is an animated series created by Joe Murray. The show aired for four seasons between 1993 and 1996 on Nickelodeon. Rocko's Modern Life is based around the surreal, parodic adventures of an anthropomorphic wallaby named Rocko, and his life in the city of O-Town. Originally from Australia, the show explores his American life as well as the lives of his friends: the gluttonous steer Heffer, the neurotic turtle Filburt, and Rocko's faithful dingodog, Spunky. The show is laden with adult humor, including double entendres, innuendos, and satirical social commentary. Joe Murray initially created the title character for an unpublished comic book series in the late 1980s, and later reluctantly pitched the series to Nickelodeon, who was looking for edgier cartoonists for their new Nicktoons block. The network gave the staff of the program a large amount of creative freedom, the writers targeting both children and adults. The show's animation's stylistically features crooked architecture. In addition, Murray picked a large amount of newcomer voice actors, such as Tom Kenny and Carlos Alazraqui, whave in recent years gone on to become very popular. The show was the fourth Nicktoon to premiere.
