Your information is not right. Krampus is not the twin of Sint Nicholas but his helper just like "Zwarte Piet" is in the Netherlands and Belgium.
Both stand for the guy with the bag, collecting naughty children and carrying them to... With us it is told Spain but I never ended up there although I could use a long (forever) holiday in a better climate.

I think it's good if you spread the news you info first.

Also in Germany and more eastern European Countries Sint Nicholas is celebrated on December 6th and this celebration has nothing to do with the coca-cola guy introduced to forget about the real meaning of Christmas.
