In episode 3 of season 2 Testpiet goes to a pharmacy shop to buy chocolate letters instead of going to the home kitchen of Saint Nicholas (in the castle where she lives) where chocolate letters are being made. Coincidentally in the next scene Coole Piet and Danspiet show the chocolate letters 'C' and 'D'; the letter C is the first letter in the name of Chefpiet (the cooking Black Pete in the castle) while the letter 'D' is the first letter in the name of Don van Dijke (the actor that plays the character Chefpiet).
