Remember how we were explaining that the four races in Final Fantasy Crystal Chronicles: Ring of Fates are different? Selkies have a bow, which lets them shoot objects at a comfortable distance away from the action. Their bow also comes in handy to hit far away switches as seen in this video.
Did you notice all of the double jumping in the Selkie hit the switch? It looks like Square-Enix is adding in platforming elements into the game too, which were absent in Final Fantasy Crystal Chronicles for the Gamecube.
