Here's a very special Holiday Edition from my Dictionary of Mythological Creatures.

"The Alabastor: A Semisupernatural Being in the folklore of the Mari Peoples of Northern Russia.
It manifests the bath houses of humans as a giant with long flowing hair. It's activities include sexual intercourse with humans, and it punishes those who overindulge by providing such sexual excess as to cause their death from exhaustion. The attentions of the Alabastor may be discerned by a sore left on the victim's lips from it's kiss. The Alabastor may be defeated in two ways, either by catching it and breaking the little finger of it's left hand, thereby breaking it's power, or by placing a cross over each door, thus preventing it's entry."

Happy Holidays!
