Stinky Cheese Ball

This is a massive curd of extremely pungent cheese. If Little Miss Muffet had had one of these, she'd have had neither the room in her bowl nor the appetite for any whey.

When the top layer is scraped off, the cheese ball can be thrown into a room to suffocate all air-breathing creatures inside, knocking them unconscious. It essentially acts as mustard gas. Can be used 3 times.
