Thumbskull is a character in IRR. He acted like Zombozo's minion, but really just looks up to him, like his friends Acid Breath and Frightwig.


Thumbskull was a hulking figure and his size often intimidated others. He had a large chin. He also had one large finger on each hand, complete with a single fingernail, and a single thumb on either hand.

History and Personality

Thumbskull has always been friends with Acid Breath and Frightwig, as long as anybody had known him. They were found on the street as teens by Zombozo, and continued with him the rest of their times. He didn't like to talk to people, and mostly communicated with the rest of the trio through motions.
