Cereal is less of an issue in the first place (that's a very US thing, didn't even know it existed till I moved to the US when I was 10), but you just don't find brands associating themselves with characters from movies/tv shows.
The closes you get it Sinterklaas/Zwarte Piet on seasonal items and Santa Claus.
Action figures are something you have to get at a specific toy store. Large "super store" like WalMart/Target/others don't really exist. I can't go buy a couch at Albert Heijn. I don't go buy a TV at Aldi. In the US however going to Walmart for electronics is as normal as going to get groceries.
