Luffy and company come across a mysterious pirate ship after trying to escape a giant wave. Soon, they arrive on an island inhabited by strange animals. Going Merry is captured by the Foxy Pirate crew.

After Tonjit re-unites with his horse, they are soon attacked by Captain Foxy and his subordinates, who challenge Luffy in a Davy Back Fight, a contest of pirates where the stakes are members of the crew.

The first round of Davy Back Fight involves a race around the island with tiny boats. Zoro's and Chopper's boat is eliminated.

With only Luffy, Nami, and Porche's boat remaining, it's an all out war to the goal, but after Foxy exposes his Devil Fruit powers, Porche wins and takes Tony Tony Chopper from Luffy. The second round prepares to start.

Without Chopper, Sanji and Zoro must face the Foxy Pirates in a ball game, but are hampered by their blatant cheating and the crooked referee.

The bickering rivals Sanji and Zoro manage to overcome the opposing team by working together. Luffy chooses Tonjit's horse, Shelly over Chopper.

The Straw Hats face Foxy a race around a giant ring on roller skates.

Thanks to to some quick planning, the Straw Hats win the race.

With Luffy's victory, he takes Chopper back, but foolishly accepts another challenge by Foxy.

Foxy decides to take Robin from Luffy this time because of her Devil Fruit ability. The next match is a race to the top of the island.

With Chopper gone again from Luffy's crew, Luffy and Foxy face off in the final game: a battle of brawn aboard Foxy's ship.

Luffy continues to battle Foxy with the odds not in his favor, and the fight continues inside Foxy's ship.

Luffy manages to finally defeat Foxy by using his ability against him. After dismissing his new crewmembers, the Straw Hats leave in search for a shipwright.
