In Iceland, there's not really a Santa Claus figure at all, Gunnell said. Instead, there's the "Christmas Men," also known as the Yule lads. As the stories have told it, the mystic men – with names like "Window Peeper," "Sausage Swiper," "Bowl Licker" and "Meat Hook" — come one by one down from the mountains by your community, play pranks and steal things from homes. (To be fair to them, they'll also leave presents in windows for children.) On top of that, they have an ogress mother, Grýla, who eats misbehaving children "like sushi for Christmas," Gunnell said.
And although he doesn't swipe sausages or eat children, Santa Claus is not a completely dissimilar figure.
