Dirt man is a green character who eats dirt, lives in a trashcan and vaguely resembles Oscar the grouch from the TV show "Sesame Street". His trashcan is like the "tardis" from doctor who, in that it is bigger on the inside. Dirt man is actually one of the most intelligent characters in the Revenge of the Sunfish series, this is hinted at with the "e=mc*" formulas that haphazardly appear on his stage.
