The iron teeth of Baba Yaga are sentient, magical, and airborne dentures that sometimes work at cross-purposes to the Old Witch. If the teeth and Baba Yaga are getting along, the teeth reside inside her mouth, providing her with a bite attack and access to its spell list. Baba Yaga can cast a spell from the teeth's innate spell list as a bonus action, using her spellcasting ability. Spells cast in this way are removed from the teeth's spells per day total. If the witch and her teeth are not getting along, the teeth will fly around casting its spells as it wishes (often to the benefit of Baba Yaga's enemies).
