Don't remember Yo-yo ball, but I do remember Pogo Ball, which was pretty lame, in fact I can think of nothing fun about it.
In the same category, I think anyone who owned "Skip-it" should be pistol whipped.

Speaking of water based toys also, there were those tiny (about the size of a pill) items that were shaped like different things. then you put them in a sink or the bathtub and they expanded to the size of your thigh.

Actually, I can't decide whether those sucked or not...
