Babayaga

Babayaga is a Slavic type of medieval Hag, who regularly catched and then ate children for breakfast, and presumably for other meals, as well. They lived in well-hidden huts that stood on giant chicken legs and usually situated close to forests. Babayaga also had a gate surrounding her house, made of human bones. These could have been made from the children she ate. She appears in many Muggle fairy tales as an antagonist.

Behind the scenes

 * The name Babayaga is presumably based on the legend of the Baba Yaga.
 * She appears on a Chocolate Frog Card.
