A scary creature that lives under your bed. Your objective is to get it onto your ceiling. If you look under your bed and its awake it screams in your face then eats you. Biggie smalls and Tupac looked at it when it was awake and they died. After you get it on your ceiling you dont die. When people walk buy it kills you. Lol!
