He grew up being raised by a single parent (as with most Uncle Grandpa characters are). At the beginning of this episode he is celebrating his thirteenth birthday party. He then leaves to go break stuff with his friends, due to the fact that he considers the party lame.
Personality and Appearance
He's a short and chubby kid with blonde hair, sunglasses, and big lips who likes to "look cool" and break things with his friends. He is quite judgmental and dismisses many things as "lame."
