Advent 13

Icelandic children get to enjoy the favors on not one but 13 Father Christmases. Called the Yule Lads, these merry but mischievous fellows take turns visiting kids on the 13 nights leading up to Christmas. On each of those nights, children place one of their shoes on the windowsill. For good boys and girls, the Yule Lad will leave candy. If not, the Yule Lads are not subtle in expressing their disapproval: they fill the shoe with rotting potatoes.

Describe one of the Yule Lads.
