"Krampus"
His appearance is befitting of a demon. Dark matted fur with cloven hooves and large horns. His tongue is long and pointed and his teeth are sharp fangs. He is described as carrying chains or ruten, bundles of birch branches, to hit bad children with. Other times he is depicted with his sack, or even a washtub, which he uses to carry naughty children to the underworld where he will later torture and possibly even eat them.
