a shoe in a dog's butt

I didn't hear anything from Dylan for a couple minutes, and when I turned down the hall to check on him, I find him with this in the bathroom. With water dripping from his hands, water covering the floor, and the toilet lid up, I asked him if he was putting his toys in the toilet. He said no, but then seemed to think about it, and got a smirky little smile on his face and asked, "I scoop water with my pup?", and then scurried away to destroy something else.

By the way, Dan thinks this looks like a toddler prison shank. Hopefully it's not a sign of things to come.
