I can't really think of anything, but I know there's tons.

The first thing that popped up for me was squand, if anyone knows what that is. It wasn't even that fun but it was just so weird. It was that colored sand you could put in water, yet no matter what it was dry when you took it out. There must have been a gypsy curse on it.

It was always fail though because there was never a decent way to put it all back in the bottle, unless you used maybe a funnel.

Buuuuut, of course I wasn't that smart as a child :s

Omg and count chocula wtf!
