Baby Bottle is a baby in the shape of a literal baby bottle, with an off-white body and red top. He has a red button-nose and has one tooth sticking out of his mouth. He wears a light blue smock, similar to old-fashioned baby clothing, and white gloves. Baby Bottle outwardly looks like a normal baby, easily gain the affection of anyone he meets, and will call people he likes "Mama" (notably Mugman and Elder Kettle). However, he has a devious streak, and will cause mischief with no remorse for his actions. When the person he likes inevitably disapproves of his actions or call him a "bad baby", Baby Bottle will say "Mama" disapprovingly, and subsequently beat the person up with superhuman strength.
