JAIL Oliver my boi.

Oliver has knee-length white hair that is tied into a bottom ponytail with a black bow. He has two black horns and a red circled "A+" mark on the right side of his hair. He also has a large split ahoge atop his head. Additionally, his right arm is replaced with a pencil. Strangely, his tongue appears forked, similar to a snake's.
His outfit consists of a short-sleeved, orange inmate shirt over a long-sleeved white shirt that matches the long orange pants.
