Gruß vom Krampus!
Krampus is a beast-like creature from the folklore of Alpine countries thought to punish bad children during the Christmas season, in contrast with Saint Nicholas, who rewards nice ones with gifts. Krampus is said to capture particularly naughty children in his sack and carry them away to his lair.
Generally demonic in appearance, the creature has roots in Germanic folklore. Traditionally young men dress up as the Krampus in Austria, southern Bavaria, South Tyrol, Hungary, Slovenia and Croatia during the first week of December, particularly on the evening of 5 December, and roam the streets frightening children with rusty chains and bells. Krampus is featured on holiday greeting cards called Krampuskarten. There are many names for Krampus, as well as many regional variations in portrayal and celebration.
