A real Dutch tradition: Sinterklaas! To help the helpers of Sint Nicolaus, the Pieten, we’re going to do the official Pietengym workout that they have to perform in order to climb on all those roof tops, and deliver presents to all the children. At the end if you pass the final test, you will get your very own Pieten diploma! Afterward the training you will be rewarded with some chocolate milk and pepernoten!
