Here he is making the bottom of the ship. I'm not sure why it's wrinkled, or why it's pointy. The mast of the ship is his shark head grabber toy that he got with some of his tickets from Hoover library.
When I told him to pick it all up, he asked politely if he could leave it all day, because he promised his imaginary diving club patrons that they could spend the afternoon snorkeling. I told him they snorkeled while I took pictures, and pictures of his Great Barrier Reef will have to be good enough--I want to be able to get to my bedroom without drowning (or being eaten by a shark!).
