Back yard summer fun

This is the "capri sun pool" as Thomas calls it. I asked him why he calls it that. He said "I don't know. Because it is." I don't know if he calls it the capri sun pool because it has a beach scene decorating the outside walls or if it is because the weight of the water is what holds up the walls, like in a capri sun juice pouch. Things that make you go, "Hmmm...What goes on in his head?"
