An anthropomorphic black 8-ball who might have a favorite number. He has no limbs, so he rolls. He's good at being a leader, when he's not purposefully being sarcastic. He can lead, but can't come up with good ideas. A joker. His favorite number is 8, but he keeps that very secret. Really good friends with Basketball, Robot Flower, TV and Grassy. Feels impartial to Tennis Ball and Blocky. He had a rivalry with Golf Ball, which he felt bad for. They made up since.
