The Icelandic Yule Lads are the sons of the trolls Grýla and Leppalúði. They come down from the mountains, one each of the thirteen nights before Christmas bringing children small treats In the days of yore however, they were anything but nice. Instead of bringing treats, they came to scare peple and steal what was most precious to them, their food.
The second Yule Lad is Giljagaur (Gully Gawk). As stealthy as a shadow he threaded the gullies down from the mountains, to avoid being seen. He hid in the cow barns waiting for a chance to skim the cream off the milk when the farmer wasn't looking. I don't know how that's going for him with all the automated milking equipment these days. Fortunately he's mostly leaving treats in little shoes instead of stealing milk.
