De Grote Sinterklaasfilm en de verdwenen verlanglijstjes

Every year, Sinterklaas and the Pieten eagerly look forward to their big journey to the Netherlands. In the castle, preparations are in full swing. The two new "Pieten-in-Training" (PIO's for short) are soaking up everything like sponges, eager to prove themselves. Everything seems to be going according to plan until disaster strikes. Jean-Claude takes a nasty tumble down the stairs and ends up bandaged. To make matters worse, his Aunt Poets suddenly shows up at the castle. She insists on taking over the housekeeping.
