Well I think the main reason Abe is blue is because partly he's the choosen one and partly because he's really depressed. I mean if you where told you where the savior of your race and that you had to go through all sorts of different trials, etc. then I don't think you'd be to happy. Even if you where you would soon be screaming, crying, and running at the same time as you escaped from a pack of angry Paramites. Abe's life is really stressfull, he's always on the move (even though all Mudokon tribes are) to new places with more problems that are up to him to solve...
