Strangely, even though Heffer is male, he has been shown on a number of occasions to have udders. As his last name suggests, he was raised by a family of wolves who decided not to eat him as a child and adopted him instead. Heffer is also known to have a double life. When Filburt was having children, some of his children had the appearance of Heffer, which everyone seemed stunned and suspicious.

Filburt also seems to have an obsession with fish sticks. He was married to Dr. Hutchison in the shows third season, with whom he has four children. Among Filburt's catchphrases are "Oh fish sticks!" and "I'm nauseous... I'm nauseous... "
  • The Bigheads: The Big heads are known to be odd. They are also known to act very sexual.Though it is very discrete and the kids probably do not know what is happening. In one particular episode it is shown that Ed and his wife, Bev, were high and chasing each other around like zombies.
    • Edward Bighead (voiced by Charlie Adler): A grumpy old toad who is Rocko's neighbor. He hates Rocko despite Rocko normally acting nice to him. Ed works at the large corporation Conglom-O.
