Personality
He became addicted with the game Galaxy of Death 2, and all he does basically for a whole week. He also always has mints and a lot of times gives them to people saying, "Have a mint." He is mentioned by Gabe as crazy while he is hiding from his grandfather. Bob replies, "One more thing him and Grandma have in common," because she locked him in a room.
