In the Netherlands, Sinterklaas (Saint Nicholas) visits children on December 5. In the Anglophone world, Santa Claus has elves as helpers and lives at the North Pole, or maybe Lappland. In the low countries he has Zwarte Piet (Black Peter).
Originally Zwarte Piet was a devil Saint Nicholas had triumphed over. In later stories, he became a servant from the colonies, and Sinterklaas and Zwarte Piet began to arrive on a steamboat. Zwarte Piet brings gifts and sweets to children who have been good, but if they've been bad, he stuffs them in a bag and carries them away to Spain where he lives the rest of the year.
The Netherlands doesn't have a taboo against blackface, but the fact that Zwarte Piet's appearance and characterisation can be problematic has not escaped the Dutch.
 In Belgium he visits on December 6, giving him two days to get around both countries, which is probably plenty of time.
 Santa Claus is sometimes characterised as an elf, which, to those of us with a passing knowledge of folklore, clarifies why he doesn't bring the gifts you want, or need, or even deserve, but instead, whatever the hell he feels like.
 If they've been a little bit bad, they get no present, and rather than being carried away they get a birching. With corporal punishment falling out of favour in modern times, he instead presents them with some coal.
