"I'm from The Netherlands, and I can't say for certain, but I can't remember a product being sold at a grocery store that had characters from a children's TV show/movie on the label to try and sell it"

What? You mustn't have any children. There is cereal of Frozen and Moana here, Paw Patrol sprinkles, k3 stuff (forgot which), there's various franchise stuff in the dairy section, ... That's not even counting the non-food section in supermarkets. Next time you're at albert heijn, take a good look around.
