Y'know, I'm kinda surprised he doesn't turn into a hoop when hanging onto something.
Hey, maybe give him the ability to "switch" things to morph into using the weaponnext/weaponprev buttons? Like, along with there being a simple spike ball, he could morph into a boat to travel across water with more control or a fish net to catch enemies or other players to slow them down until they manage to shake 'em off? I can't exactly come up with much more things for the slime to morph into at the moment, but I'll be glad to see anyone else come up with their own ideas.
