One Piece

Robin suggests that only those who were sleeping lost their memories. Luffy and the others then remember seeing the mysterious boy who played some kind of flute. Later that night, they discover the boy outside and Luffy tries to fight him. At the last second, he proclaims his memory has returned.

During the night, Usopp, Chopper, and Sanji question what brought them to the Going Merry. In the morning, Usopp builds them a raft and they sail to the island where they meet Nami again. Meanwhile, the boy sets his sights on Zoro.

On their way to "The Palace of the Sea God" Robin's group meets an entranced Zoro. It looks like Zoro wants to fight so Luffy urges the others to keep going without him. They apprehend the kid but the whistle was what was really stealing their memories. Zoro returns, still entranced, but Luffy's nowhere to be seen.

Luffy returns and knocks some sense into Zoro. Cornered, the sea horse spreads illusions of the people in their memories to distract them. It steals their complete memories and claims that it has become a Sennenryu. Luffy defeats it and returns all the memories but the townspeople are convinced they are the memory stealers.

Luffy rescues Foxy, Hamburg, and Porche from a storm at sea. When they reunite with the Sexy Foxy ship, they find it captained by somebody new. Foxy accepts a Davy Back Fight in order to regain his ship and crew. Donning the afro once again, Luffy vows to defeat the captain.

Once Foxy wins back his crew, he captures the Straw Hats. Nami and Luffy fight Foxy and although he's defeated, his crew accepts him back. Later, they sail to an island where they meet someone Robin knows: a Marine named Aokiji.

The man they met, Marine High Admiral Aokiji, appears to be incredibly lazy. He first displays his Devil's Fruit ability by freezing the sea so some deserted people can get off the island. Unfortunately, he's determined to catch Robin. Luffy, Sanji, and Zoro attack but they seem to be no match.

Robin is frozen by Aokiji and Luffy tells the others to escape with her. In the Going Merry, Usopp and Chopper try to thaw her in the shower. Luffy gets defeated (frozen), but his life is spared as Aokiji believes he must repay the debt the marines incurred from Crocodile's defeat at Luffy's hands. With the crew defrosted, they continue sailing as usual. Zoro spots the giant frog they heard about and they chase it to an island with a lighthouse, but it appears they'll sink before they get there.
