— Cornelius, leaving Zack and his friends, "Field of Screams"
Uncle Cornelius is a farmer that works hard and could use the extra help. He is also the uncle of Zack Underwood.
He appears to be very loving and trusting especially to his family. This is shown when he trusts Zack to take care of his farm, even when his brother thought Zack couldn't handle it.
He wears a red plaid shirt over a white shirt. He wears blue overalls with yellow gloves. He also wears brown shoes with a green, yellow, and black hat. He has brown skin with gray hair and mustache.
