Summary
After the Ocean's Dream arc, the Straw Hat Pirates are caught in a storm. By chance, they come across Foxy, Porche, and Hamburg, who are by themselves on a small boat. Despite Foxy using his ability to stop any waves from hitting them, the ship is in danger of being turned over, so Luffy pulls them onto the Going Merry. They are allowed to stay on the ship for now, and the next day they come across Foxy's ship, the Sexy Foxy. Foxy has a tearful reunion with his crew, until it's revealed that they are now under the command of the Fanged Toad Pirates, who had taken over in Foxy's absence. Foxy is about to leave, but the new captain points out that his crew refuses to swear loyalty to him, and that he will have to beat Foxy up to get it. In response, Foxy challenges the captain to a Davy Back Fight and calls for the first match to be Captain vs. Captain.

He uses his Noro Noro Beam, but it is reflected back at him by the swords of the crewmembers loyal to the Fang-Frog captain, who proceed to gang up on him. Hamburg tries to help Foxy using his club, but the captain takes Porche hostage, forcing him to drop it. Luffy yells at the Fang-Frog captain since it was Captain vs. Captain, but he points out that he never accepted the match, and after more attempts by Foxy, Luffy rushes in to help him. Foxy gives Luffy his afro once again, and with this the Straw Hat crew beats up the Fang-Frogs. For his effort, Foxy uses his ability on the crew and activates a trap door that drops them into his ship. Inside, they come across several traps but eventually manage to escape. Foxy's crew strikes again on an island using a special crab submarine, but this once again ends in failure. This leads into the encounter with Aokiji.
