In the lower right you have a panicked mass of people trying to escape the man on the diving board. Well, actually, trying to escape the shark underneath the man on the diving board… There’s also a lot of people with cameras in this puzzle, occasionally filming scantily dressed women. That’s the Dutch humor for you.
And of course the usual random floating hand coming out of unexpected places, a trademark of his. No Sinterklaas in this puzzle, though.
