I'm say beachballs and ride-ons
I like riding down beachballs as I deflate them. I really want one of those big 36 or 48" balls^_^. I like ride-ons too^_^. It's fun to ride them down while deflating them
And, they're usually made with fairly durable vinyl, so they usually hold up pretty well
Unless you inflate them past their limit
I really want one of the PuffyPaws Wolfs, but they're pretty expensive, and nearly impossible to find now. If anything, I'd love a chance to ride one^_^.
