the answer might be only one
(not sure about it)

Answer 2

"The answer is “Iceland.”

The Christmas instead of starting from December 25th begins on 12th of December at Iceland, 13 yule lads from the mountains descend to carry out the mischiefs.

Children keep their shoes out on the window sill, and as the days pass by, the yule lads come one after the other and leave gifts in the shoes of well-behaved kids, and a potato in the shoes of the naughty kids. Kids could drop some snacks or bread for the yule lads as well."
