Krampus is the original Chrismas baddie, the demon-like character that shows naughty kids the error of their ways with a bit of night terror.
Every year a procession of Krampus' (Krampi?) take to the streets in Austria and Germany as both a nod to the old holiday traditions and a gentle reminder for kids to stay on their best behavior.
