He wears a large shirt that has orange patterns traveling along the collar, the bottom of the shirt, and the sleeves. Another unusual feature about Fatkat is his teeth, which unlike the other characters who have buckteeth, he has single showing, like Cro-Marmot. His ears also seem to be different from the other tree friends, ending in points instead of curves.
