hehe, well played rubah

you can obtain the sources by morphing the enemies aboard the sunken Gelnika but as Cpt. Maxx power said it's completely unnecessary in this game.

to obtain power sources easily, morph the rhino tank things at the exploded reactor in gongaga, much easier than it is on gelnika.

also use yuffie and her ultimate weapon when morphing as it's special ability will prevent it from doing less damage when morphing
