In Slavic folklore, Baba Yaga is a supernatural being who appears as a deformed and/or ferocious-looking woman. Baba Yaga flies around in a mortar, wields a pestle, and dwells deep in the forest in a hut usually described as standing on chicken legs. Baba Yaga may help or hinder those that encounter or seek her out. She sometimes plays a maternal role, and also has associations with forest wildlife. According to Vladimir Propp's folktale morphology, Baba Yaga commonly appears as either a donor or villain, or may be altogether ambiguous.
