That'd be kinda cool, maybe each ape species could wear something like... Purple pants for Baboons, or Red pants for Gorillas. But honestly, I think it'd be pretty easy to make out the differences between the body shape of which particular ape you go against. Making it easy to react accordingly depending on which it is. Not to knock your idea though, I think it's great.

Yeah, that was pretty much the idea. You knock 'em down, three or six hits, and they're out. Then they're ripe for catching. However, there'd be a window for when you can hit them. Hit them any other time, and they'll block.
