"A female demon of Japanese lore who appears on snowy nights. She is a type of Yuki-onna who freezes and kills humans. Sometimes she appears with a baby and asks travellers to hold it for her. The baby gets heavier and heavier and if you drop it she will kill you, but if you can bear it she will give you strength."
