Hmm, a non-intuitive puzzle isn't really a puzzle anymore, is it? Q: I have three oranges and one grapefruit. I have to get all of them through a door that's been glued shut. There is no way to open the door. How do I get the fruit through? A: Blend them and use the tube lying next to the door and pour them through the keyhole. That's a non-intuitive puzzle. You can't intuit that there's a keyhole, a tube and a blender accessible. With creativity it's solvable, but then again, with creativity you also could argue you could use the hole saw nearby and cut a hole in the door and deposit the fruit on the other side. At this point you're just making things up.
