Paul Z. asked me if this teufel was Krampus which prompted an immediate wiki search to find out that yes, this guy could be Krampus. Wiki says:
Krampus is a mythical creature who accompanies Saint Nicholas in various regions of the world during the Christmas season. The word Krampus originates from the Old High German word for claw (Krampen). In the Alpine regions, Krampus is represented by an incubus demon accompanying Saint Nicholas. Krampus acts as an anti–Saint Nicholas, who, instead of giving gifts to good children, gives warnings and punishments to the bad children. Traditionally, young men dress up as the Krampus in the first two weeks of December, particularly in the evening of December 5, and roam the streets frightening children and women with rusty chains and bells. In some rural areas the tradition also includes birching by Krampus, especially of young females.
Modern Krampus costumes consist of Larve (wooden masks), sheep's skin, and horns. Considerable effort goes into the manufacture of the hand-crafted masks, and many younger adults in rural communities compete in the Krampus events.
In Oberstdorf, in the southwestern alpine part of Bavaria, the tradition of der Wilde Mann ("the wild man") is kept alive. He is like Krampus (except the horns), is dressed in fur, and frightens children (and adults) with rusty chains and bells, but is not an assistant of Saint Nicholas.
