I've an idea. I don't know if anyone has said anything like this, but perhaps all Mudokuns could have throwing rocks as a secondary medium range attack. Or all natives even.
And this might be thinking way out there, however maybe Munch and Abe could be considered 'Heroes' of sorts that are only unlocked after a certain amount of points (or whatever) are achieved, or if not that, just their spritual/scientific counterparts (Skrykull, Brute). Just an idea thrown into the pile.
