Episode 529

"Fishman Island Collapses?! Shirley's Prediction" is the 529th episode of One Piece.

Summary
Chopper, Camie, Luffy and Usopp look for a blood donor for Sanji after he suffers a life-threatening nosebleed. They all eventually find two okama donors who were willing to give blood (much to Sanji's demise). While Chopper looks after Sanji, Camie brings Luffy and Usopp to meet Madame Shirley in the back of the Mermaid Cafe. After Luffy and Usopp notice Madame Shirley's crystal ball, she advises them to not touch it because she doesn't plan on using it anymore. Camie then informs Luffy and Usopp that Pappagu was away to see an old friend, who is later revealed to be Brook. Pappagu later states how he found Brook on a log drifting along the river. Meanwhile, Ishilly and her other mermaid friends decide to open a barrel that appeared with Luffy, Chopper, Sanji and Usopp when they were drowning, only to all disappear after opening it. At the end of the episode, Madame Shirley is yelling in horror to the townspeople after looking into her crystal ball that she pre-visioned Luffy destroying Fish-Man Island and demanded that he would be thrown out of there.
