Rocko's Modern Life was an animated series on Nickelodeon that ran for four seasons from 1993-1997. One of the more famous things about the show was that the B-52's did the opening theme song. The show concentrated on the life of a wallaby named Rocko trying to survive everyday modern life.

Filburt Shellbache: Rocko's other best friend, a neurotic turtle; started out as a background character; lives in a trailer.

Wolfe Family: The Wolfe family could actually have a show of their own. The Wolfe family adopted and raised Heffer. Virginia is the mom and always treats Heffer like a little kid. George is the father, who would like Hef to grow up and get out of the house. There is also Peter and Cindy, brother and sister, but not much is known about them. They also have a grandpa named Grandpa.
Ralph Bighead: Ralph is Ed and Bev Bighead's son. He was disowned by Ed for not wanting to work for Conglom-O, so he went to Holl-O-wood to become a cartoonist. He created a cartoon called The Fatheads. The creator of Rocko's Modern Life, Joe Murray, does the voice of Ralph.
Really Really Big Man: A superhero that lives in O-Town. He is very big and is depicted as a kind of political drawing superhero.
