Krampus
On the eve of St. Nicholas’s Day, Austrians celebrate the Krampuslauf (Krampus Run). The Krampus, represented by costumed revelers, is usually depicted as a dark,cloven-hooved beast covered with hair, red horns on his head, a malicious mouth, chains and a switch. He visits the children on Santa's Naughty List.
Children are invited to throw snowballs at the Krampus.
