Grubber is one of the members of The Gangreen Gang (a gang of monstrous teenaged hoodlums that are green-skinned and disreputable and unhealthy looking (as if suffering from gangrene). Grubber is the Gang's most physically grotesque member- untidy hair, enormous chin, ragged, grubby clothes, a long tongue hanging out, and protruding eyes, resembling an Ed "Big Daddy" Roth cartoon and looks as if he has been living in a cave all his life. He also appears to be mostly mute, communicating instead through blowing a raspberry. His father resembles him and has the same speech pattern. He does, however, occasionally demonstrate unexpected talents, such as playing the violin, speaking eloquently or performing impersonations (at first, they were so obvious it was a wonder how he fooled anyone, but later he was able to do them perfectly). His full name is Grubber J. Gribberish. He is same age as Snake and Billy - The middle aged members of the Gang.
