His real name is apparently Room. Gender is unknown. He is a humanoid monster with black skin and two eyes; his ears are extremely pointed, and he has no mouth. He is terrifying. If you hide in a wardrobe, he will wait for you to come out before eventually leaving. He does not attack if you are in the lobby. He does not speak; if you hear a high-pitched, ear-splitting ringing sound, it means he is chasing you. You cannot defeat this guy physically.
