Save Nami! Luffy's Fight on the Snow-Capped Mountains!

Chopper tells the others that Nami was kidnapped by the Yeti Cool Brothers. Luffy and Franky go after them, but Franky (in Chopper's body) goes against Chopper's warnings and takes a rumble ball, going on a rampage and chasing Luffy. Meanwhile, Caesar notices Vegapunk's beam in Franky's body and craves for it, he calls his men so they go to the fire side gate and see a cave. After Luffy nearly falls into a trap he faces the Yeti Cool Brothers when Franky ending up beating one of them before his rampaging forces Luffy to knock him out. The second brother tries to escape with Nami before Law appears and defeats him. Law then proposes an alliance to take down an Emperor to survive in the New World.
