Oh Krampus... You devil you. I heart Krampus! Definitely lying to my children about him! You better not pout, you better not cry, you better not shout I'm telling you why... Krampus is gonna beat you down!
If the Elf on the Shelf isn't working, try a threat from Krampus! This is the original elf. The roots and true, hidden meaning of christmas is paganism. Seek truth. Jesus is not the reason for the season.
Krampus is a beast-like creature from the folklore of Alpine countries thought to punish children during the Yule season who had misbehaved, in contrast with Saint Nicholas, who rewards well-behaved ones with gifts. Krampus is said to capture particularly naughty children in his sack and carry them away to his lair.
