You may not know about Krampus, but I can guarantee you that the children of Austria know him. He's Santa's sidekick, the one who does all the less pleasant Christmas duties. You know, like putting coal in stockings and hitting bad kids with switches.
Description: horned head, foot-long tongue, hooved feet. Hmmm.
Krista said, "He looks evil." This is the nicest picture I could find of him. This is the sort of cute version from old postcards.
Note to Missionaries: If you are creating a Christian festival to take place at the same time as a pagan ritual, please be sure to get rid of critters like Krampus.
