Rocko's Modern Life was a 1990s Nickelodeon cartoon known for its twisted sense of humor. The series centers on the surreal life of an anthropomorphic Australian-immigrant wallaby named Rocko as well as his friends: the gluttonous steer Heffer, the neurotic turtle Filburt, and Rocko's faithful dog Spunky.
- Rocko Wallaby (Carlos Alazraqui) – A young adult Australian wallaby who lives a troubled and "modern" life wherein the entire universe seems to shit on him. Being the show's "everyman", Rocko has had several jobs over time, including: an eternally-abused cashier who has beverages in his face, a telephone mating counselor, a highway decongestant, a plumber's assistant, a co-creator of the critically-acclaimed television series Wacky Deli, and a high fashion model for the wife of Victor Yeltosky.
- Heffer Wolfe (Tom Kenny) – A morbidly obese cow who was raised by wolves, hence his counterintuitive last name. He is a total slob when eating, eating only the unhealthiest foods such as chips, soda, and ice cream, despite nearly dying after suffering a heart attack from eating too many Pasture Puffies.
- Filburt Shellbach (Doug Lawrence) – A nervous turtle with unbelievably bad luck. He often feels uncomfortable or disturbed, punctuated by his catchphrase "I'm nauseous, I'm nauseous."
- Spunky (Frank Welker) – Rocko's anxiety-ridden dog. During a brief nervous breakdown, Spunky repeatedly sexed Rocko's mop until the local psychiatrist snatched the mop from Spunky and proceeded to watch Debbie Does Dallas while snuggling with the mop. Spunky may have some sort of sexual desire for all inanimate objects, as he proceeded to have sex with the fire hydrant and many other household objects. This dog is the idol of a large club of animated bestiality lovers.
Rocko was born from creator Joe Murray's fits of boredom, where he would draw cartoons of his surroundings (bacteria and people arguing about the mashed potato theorem). He pitched a baseball about these things to Nickelodeon, which turned it down because they thought it would get children to emulate these behaviors.
One fateful day in 1993, Joe Murray came up with a new idea: Change everyone to animals, and make them do the same things. This, Nickelodeon could tolerate.
