The Poisonous Bellows, or Toxic Bellows, is a Legendary Weapon in the games Gauntlet: Legends and Gauntlet: Dark Legacy. It lies in the Mystic Pyramid (in Dark Legacy) or the Tombs of the Undead(in the Dreamcast version) of the Desert Lands and is useful against the Spider Queen of the Forest Realm. When used it causes the Spider Queen to writhe in pain before turning green. This doesn't have any lingering effect on the boss and is probably just an animation used to signify the weapon damaged the boss.
