I posted on the OP's other thread as I actually knew some of the answers! In case anyone has any interest....
Mummering was actually outlawed in Newfoundland in the 1800's, but had a resurgence in the 1990's after the fishery closed (I was in Newfoundland in December, including several outports shortly after the fishery closed). I don't know if this was to draw in tourism, but during that period after the closure of the fishery there were a lot of creative attempts to bring people to the province. Mummering is a UK and Irish tradition and occurs after Boxing Day.
Belsnickel is the Pennsylvania Dutch version of the Bavarian Krampus, who visits on December 6th. I have encountered him in the Mennonite community in Pennsylvania. Unlike Nikolaus, he is not always just kind and giving. He also hands out punishments.
Krampus is common to remote areas of Upper Bavaria and Austria.
Both Krampus (Belsnickel) and Mummering have somewhat violent elements to them. In the town over from ours one year a young man was electrocuted on Krampus, and there were several violent incidents each year.
As many have posted that they have not heard of Belsnickel or Mummering in Canada, in Germany most have not heard of Krampus.
(oh, and that pickle? ask any of us 82 million Germans and I suspect that they will tell you that they only heard of it at Epcot and here on this website

)
