One Piece: Giant Mecha Soldier of Karakuri Castle
The Straw Hats visits an island, known as Mecha Island, where a fisherman sings an old folk song about a Golden Crown. Searching for that mysterious treasure, they find a hidden entrance into the island. The island's leader, Ratchet, impressed with the find and in search of the Golden Crown himself, invites the crew to join him in his search and the crew along with Ratchet and his henchmen enter the cave. As it turns out, the islands true form, is that of a giant turtle.

Now the Straw Hats have to stop not only Ratchet, but also the helpless turtle, from crashing into a nearby island.
