For the life of me, I can’t think of it and it’s making me crazy. Bonus points for linking to a picture of one.
It’s a toy you see often at fairs and such, but we used to see them at Kay-Bee toys, too. It’s like a skinny, thick balloon filled with water. The idea is to hang onto it, but the balloon is cylindrical and as the water goes to the bottom of the “sleeve”, it slips through your hands. You’re supposed to keep from dropping it and enjoy the oogy weird watery feeling it has.
Anyone? I could have sworn they were called “Water Willy”, but a google search on that shows that it either was never called that, or they’ve now named an adult toy that too.
