Bob is a tall, overweight adult man with slight short and scruffy black hair, some whiskers on his chin that resembles a bit of a goatee, and a wide, toothy grin. He usually wears his usual attire plus a dark-red turtleneck sweater, a red devil mask with horns, and red demon gloves. Underneath his sweater, he has a belt which holds a smaller knife, a carving fork, his knife sharpener and a salt shaker. He can be seen chasing victims with his knife and knife sharpener. His skin is pale white.
