Quick recap
Before Fish-Man Island, the crew saves the mermaid Keimi and the starfish Pappag, and meets Hatchan again, Arlong's former officer, now a good guy. On the Sabaody Archipelago, made of giant trees and bubbles, they cross paths with the Supernovas, rookie pirates with big bounties, like Trafalgar Law and Eustass Kid. Keimi is kidnapped and taken to a slave auction. There, Luffy punches a Celestial Dragon, a World Government noble, bringing an admiral down on them. Old Rayleigh, Roger's former first mate, helps them and looks after the ship. Kizaru, Sentomaru and the Pacifistas corner them, and Kuma makes the crew vanish one by one.
