He is Tom's son. He first appeared in "Summer Sucks", where he was found thawed by his parents. At once, his mother says "Oh holy Kevin honey.", and his father continues "Good to see you again son." In "Helen Keller! The Musical" it is revealed that his mother died. He is shown crying with his father over his loss.
Kevin wears a yellow long-sleeved shirt, blue jeans, and black boots. His hair is brown, and he seems to have sideburns. His appearance is similar to Jimmy's.
He was found frozen in ice in "Summer Sucks", so we can assume that he is either prone to accidents or unintelligent. In "Helen Keller! The Musical" he appeared to not understand the concept of death, although, considering his age, this is not surprising.
