Tips for survival: Billydoll is blind so he cannot see you. But he has great hearing so you must stay quiet. However, if you encounter him, your first though might not be "I have to be quiet and sneak past him." Your first thought might be "AAAAAAAAAAAAAAAAAH!" so you might not get lucky if you meet him for the first time. Try throwing something to create noise to distract him. Don't fight him. It will not go well.
How he kills you: He grabs you and swallows you whole, because he's always hangry.
