I was thinking of a little kiddy pool, but they are all tarp blue... lol so I think I might go to the pond section of Home Depot and see if they have something. It’ll at least be gray or black. He loved it!! Was the funniest thing. He would sit down and all the water would go out of it. We couldn’t stop laughing.
Bella loves her kiddie pool too! We usually get a couple trough the summer since she will play with pool (carry it around or step in it when it’s upside down) and usually put a hole it or when it is empty.
