That is Zwarte Piet, he is part of the Christmas tradition in Benelux. In the Netherlands Santa Claus has a Moorish assistant, named Zwarte Piet (Black Pete). When you take your child to see Santa Claus in Holland, there is also an actor there playing Zwartze Piet.
Zwarte Piet is always portrayed in the Christmas stories as being smarter and more clever than Santa.
Although there are african descended Dutch people, Zwarte Piet is always played by a white actor in heavy theatre make-up. To do otherwise would go against Christmas traditions.
