O.K. I'm at the very last boss of the game and I don't know what to do. I've hit his hands dodged his attacks, but he just turns right back into the masked person. I don't know if you have to try to blow up his hands and face cyrstal in on turn when he turns into a monkey person or if you have to hurt him until he turns back into the mask person and wait until he turns back and hurt him some more. PLEASE HELP!!!
