As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally gained the power to stretch like rubber...at the cost of never being able to swim again! Years, later, Luffy sets off in search of the "One Piece," said to be the greatest treasure in the world...

Before the Straw Hats can get the Merry Go fixed, they must face the Foxy Pirates in a game called a Davy Back Fight. Will the Straw Hats find a way to win the three challenges, or will they lose their crew? And what's in store when Admiral Aokiji, who knows of Nico Robin's mysterious past, finds them?
