Shiro from Slowly: You could add mavka, for example.

Mavkas are mythical female creatures that represent the souls of children who were born dead or died unbaptized. It was also believed that mavkas were children stolen by evil spirits. According to legends, they look like extremely beautiful young girls who leave behind traces of bare children's feet. The mavkas hunt for attractive young men, and those who follow them will get lost and never find their way home. There was also a myth that they "tickle" their victims, just like mermaids.
