Jimmy is a tall teenage boy with long light brown hair that goes down to his neck. He wears a light blue shirt with a yellow spot on it and a pair of blue shorts and sandals.
Jimmy acts like a stereotypical teenage boy. Jimmy seems to be very calm and laid back however, he seems depressed but he is still a fun loving guy who enjoys going out with his friends and doing fun things.
Shortly after he received the results of his IQ test which said he was of average intelligence, Dexter came to Jimmy's house and met up with him in hopes that he could teach him how to be average. He is friends with a boy named Chris. After they all met up, the boys decided to go and play a doorbell prank on Old Man McCowsky. Once it was Dexter's turn, Dexter rang the doorbell, but didn't know that he was caught as the boys try to tell Dexter to run. Dexter was then captured as the boys ran away.
