heffer wolfe is rocko's best friend, a happy-go-lucky and not-too-bright steer (a castrated bull) whom he met in high school. his appearance is basically just a big (bigger than rocko), 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 (later chewy chicken), a paperboy, and a security guard at conglom-o-corp (the last one causing him to go insane in a reference to "the shining"). 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. he is often called a "big fat cow," a term he (and his father) objects to by saying "steer." his catchphrase, which can be heard in the series' opening theme, is "that was a hoot!"
