One Piece: Giant Mecha Soldier of Karakuri Castle
The Straw Hats visit Mecha Island, where a fisherman performs an ancient folk song about a Golden Crown. They discover a hidden entry within the island while searching for the enigmatic treasure. Ratchet, the island's commander, thrilled by the discovery and himself in pursuit of the Golden Crown, invites the crew to join him in his search, and the group enters the cave alongside Ratchet and his henchmen. The island's true form, it turns out, is that of a gigantic turtle. Ratchet, who was aware of this the entire time, uses his mechanical castle to seize control of the turtle in order to use it to conquer the planet. Now the Straw Hats must save not just Ratchet from crashing into a nearby island, but also the hapless turtle.
