Like farting in a pool

I think these were the only reason Shirokiya was in business at one point. They had tons of these things. A rings one. A basketball one. Even one you had to get Darth Vader's mask onto his burnt scarred head. OK, maybe not that last one, but that would've been cool! The basic premise was simple...push the button to blow air into the water and move objects. We definitely owned the dolphin one, but not sure about the one with the crab pooping.
