Rocko's Modern Life has got to be one of Nickelodeon's greatest cartoons, but for some strange reason, is also one of the shortest lived Nick programs. While programs such as "Rugrats" and "SpongeBob" seem(ed) to live on and on - there was only ever a handful of Rocko seasons ever produced...
This cartoon starts off each episode with a great intro theme - "That was a HOOT!" (actually sung by the fantastic B52s)!
It concerns a Wallaby (named Rocko) and his best friend Heffer (the Steer). Also featuring is Filbert (the Turtle), Mr And Mrs Big Head (a couple of Toads who are Rocko's neighbors) and Dr Hutchinson (a Cat - and Filbert's girlfriend).
Rocko lives in the city of O-Town.
The voice of Heffer was supplied by Tom Kenny (who also does the voice of Dog on "CatDog", and of course he also supplies the (sometimes very annoying)voice of SpongeBob SquarePants).
