This is a list of all the major and minor characters from the animated television series Rocko's Modern Life and the comic book of the same name.
Joe Murray, creator of the series, said that he matched personalities of his characters to various animals, forming a "social caricature."
Overview
Main
Rocko
Voiced by: Carlos Alazraqui
Rocko Rama is a wallaby who emigrated from Australia to the United States. He is the protagonist of the show. He is a sensible, moral, and somewhat timid character who enjoys the simple pleasures in life. He is neat, compassionate, and self-conscious. Rocko wears a blue shirt with purple triangles, shoes, and no pants. Rocko works at "Kind of a Lot O' Comics" and his hobbies include recreational jackhammering and pining for the love of his life, Melba Toast. Due to Rocko's benevolence and non-confrontational personality, his kindness is often taken for weakness. He is often taken advantage of by the other characters. Rocko would prefer to live a quiet life, but his reckless friends often throw him into turbulent situations. His catchphrase is "Day is a very dangerous day." and even once saying "Open mic night is a very dangerous night." He is often mistaken for a weasel, a platypus, a beaver, or even a dog. The name "Rocko" is mononymous because the writers could not think of a surname that they liked. He is around 20 years old.
Spunky
Voiced by: Carlos Alazraqui
Spunky is Rocko's pet bull terrier. He has a very high-pitched bark and wags his tail a lot. He's not too bright and will eat anything on sight including Ed Bighead's salmon bushes and a moldy slime found in Rocko's refrigerator. He often drools into his water bowl and drinks it, only to drool into it again. He is Rocko's only regular pet and Rocko loves him dearly. Rocko will go to great lengths to protect Spunky if he is in danger or about to do something that is bad. Spunky is best remembered for falling in love with a mop in the episode "Clean Lovin'", much to Rocko's dismay, Spunky was noted to have used his front paws as hands as he tries to protect the mop. Spunky is also the home of two parasites, Bloaty and Squirmy.
Heffer Wolfe
Voiced by: Tom Kenny
Heffer Wolfe is Rocko's best friend, a happy-go-lucky and not-too-bright steer whom he met in high school. His appearance is basically just a big, round, yellow bull who wears red dungarees. He has two horns and a green tuft of hair on the top of his head. Heffer is an absolute glutton who loves to eat and party. His favorite food is Pasture Puffies. Though he is normally portrayed as being jobless, he has worked as a waiter at a coffee shop, a salesman at a tree farm, a greenskeeper at a golf course, a mail carrier, a manager at a Chokey Chicken restaurant, a paper boy, and a security guard at Conglom-O-Corp. As his family name suggests, he was raised by a family of wolves who decided not to eat him as a child and adopted him as one of their own, his "birthmark" is actually their plotting lines of how to best divide him up into choice dishes. In the story, "The Superb Ones" he dates a widowed. She moves in with Heffer, He is the only one who can calm her nerves, comfort her when she is saddened, and get her out of her comfort zone. He sometimes challenges her a bit and gets her into certain situations she's never tried. He loves her dearly and takes care of her. He is often called a "Big fat cow," a term he objects to by saying "steer." His catchphrase, which can be heard in the series' opening theme, is "That was a hoot!"
