Krampusnacht

You better not shout. You better not pout. You better not cry. I'm telling you why...Krampus is coming to town.

Throughout Christmas mythology, there are a lot of different dark companions to the friendly, gift-giver figures. These companions normally handle the "bad" part of that list. Krampus comes from Central Europe and is still celebrated in some regions today.

Krampus is depicted almost as a Greek satyr with both man and goat features. He is more of a demon legend than a cryptid though. 

This demon is tied to Saint Nicholas, who's Saint's day happens to land on the 6th of December but is tied into Norse mythology as the son of Hel, the goddess of the Underworld that shares her name. Where St. Nick gives out sweets to good boys and girls, Krampus, on the other hand, would swat the bad kids and even throw a few in his sack and haul them off to hell. 

On Krampusnacht, December 5th, children leave their boots outside and check in the morning whether they got sweets (from St. Nicholas) or a rod (from Krampus). In some villages, men will dress as Krampus, get drunk and go on a Krampuslauf, or Krampus (claw) run, chasing people through the streets. This fits into the Greek satyr myth nicely.
