Meet Krampus: a half-goat, half-demon, horrific beast who literally beats children into being nice and not naughty. Krampus isn't exactly the stuff of dreams: Bearing horns, dark hair, and fangs, the anti-St. Nicholas comes with a chain and bells that he lashes about, along with a bundle of birch sticks meant to swat naughty children. He then hauls the bad kids down to the underworld.
December 5th is Krampusnacht, the night before the feast of St. Nicholas. The modern traditions include parades of costumed Krampuses and parties.
The older stories of Krampus taking the bad children and the Krampus Cards from a century ago, make for some interesting, thought provoking, reading.
