Here’s another thing I didn’t know. According to Wiki, Krampus is a mythical creature recognized in Alpine countries. According to legend, Krampus accompanies St. Nicholas during the Christmas season, warning and punishing bad children, in contrast to St. Nicholas, who gives gifts to good children. When the Krampus finds a particularly naughty child, it stuffs the child in its sack and carries the frightened thing away to its lair, presumably to devour for its Christmas dinner.
In the Alpine regions, Krampus is represented by a beast like creature, generally demonic in appearance. Traditionally young men dress up as the Krampus in Austria, southern Bavaria and South Tyrol during the first week of December, particularly on the evening of 5 December, and roam the streets frightening children with rusty chains and bells.
