Christmas is supposed to be a peaceful and joyous time of year with festivities filled with love and kindness. But this frightening tradition that terrifies children in parts of Europe smashes all of the warm and fuzzy feelings associated with the holidays.
    Every year in countries such as the Czech Republic naughty boys and girls are visited by Saint Nicholas and the devil. (19) The evil figure carries a stick and is tasked with punishing children who have misbehaved over the past year, although his presence alone is enough to scare them straight.
    Footage from the Czech Republic shows the unlikely pair of Saint Nicholas and the devil, given the nickname Bertik, visiting a home in the run-up to Christmas. (20) Young children are left in fear as they hide under their beds and run to their parents to get away.
    While Saint Nicholas gives his attention to good boys and girls, the devil warns the "bad kids" they could be put in his sack and taken to hell. Children are forced to entertain the devil with a song or dance, but they’re often too terrified to make a move.
    Similar traditions occur in a number of European countries, and the most common form is Krampus, a Christmas goat-demon which punishes naughty children. The terrifying horned beast with long dark hair and fangs carries a stick to beat the kids who haven’t been nice.
    He will even lick them with his evil snake tongue. (21) The mythical creature was born in Austrian folklore and even has his own parade in countries such as Germany, Croatia and Slovenia.
