What do you do with half a ball?

This blue ball...sad thing... had a small hole. Not only did it leak air, but after being left in the rain, it inhaled water (then leaked it all over my floor). Yesterday we decided to take a real look inside it. With some scissors, I cut it in half. The boys are delighted! Now it has had more attention in 2 halves then in its spherical form. It has been a boat, a bed, a hat, a bowl, a cave, a hideout, a parking spot and probably many more things I'm not aware of.
