On Punk Hazard, Luffy, Zoro, Usopp, and Robin continue their exploration and discover that the other half of the island is actually frozen and mountainous. Meanwhile, Sanji, Nami, Chopper, and Franky discover a severed samurai's head (somehow still living) while in captivity. In their quest to escape their confinement, Franky blasts a way out and the group runs into a room of gigantic children. Brook, however, is nowhere to be found.
