You've heard of Santa, maybe even Krampus, but what about the child-eating Yule Cat?

Christmas time is upon us, and though children loathe getting new clothes for gifts, they best put on that new itchy sweater or slide on those unwanted socks. Or else risk being eaten alive by a giant cat, at least according to Icelandic folklore.

That's right. A child's worst nightmare — new clothes under the tree — could only be outdone by a somehow worse nightmare, being devoured by a ferocious feline that hunts down children caught not wearing their new clothes.

The tale of Jólakötturinn, which translates to Yule Cat, is an Icelandic Christmas classic dating back to at least 1932, according to the Icelandic Folklore website, a research project managed by the University of Iceland.
