Short Summary
The Straw Hat Pirates are finally on their way to Fishman Island! After Nami explains the properties of a coated ship, Franky reveals why Hatchi was not there to guide them. As it turns out, the Marines discovered the Thousand Sunny and tried to claim it, with Duval and Hatchi sustaining heavy injuries in the ensuing battles. Franky also reveals that before Bartholomew Kuma was fully converted into PX-0, he made a deal with Dr. Vegapunk to secretly program him to protect the ship until the return of one of the Straw Hats. As such, the Straw Hats are deeply indebted to Kuma for not only saving their lives but for protecting their ship as well. The chapter ends with the Caribou Pirates in pursuit of the unaware Straw Hats.
