Is it in the Netherlands where along with St Nicholas bringing presents for the good children, Black Peter comes with a whip to whip the naughty children?
In looking around, it appears that some variation of Black Peter exists in most of northern Europe (including the Netherlands) and Scandinavia. He's somewhat controversial because in some versions he's a Moorish slave or servant to St. Nicholas and gets depicted in blackface and foppish costumes. But he does carry either a switch or rod to punish naughty children with.
But even that's supposed to be the appropriation of the Old Norse myth of Woden, who accompanies Odin riding through the night air. Two black ravens, Huginn and Miersinn, accompany them and listen through the chimneys and tell Woden who has been good and who has been bad during the year. Good children get bags of sweets, but he is armed with a birch made from willow branches to beat those who have been naughty.
