Short Summary
The Straw Hat Pirates and the pirates on the Flying Dutchman are escaping from the erupting vulcano. As the other pirates, pulled by Wadatsumi and Ankoro, are out of sight, the Strawhats jump into a dark trench with Surume leading. They now fall, with an avalanch of stones following them that are getting closer to the Thousand Sunny. Right before being hit, Usopp saves the crew by using a Hissatsu: Midoru Boshi Saragassi, growing seaweed on the cliff, catching most of the rocks. However, some rocks fall on the head of the Kraken, and they plunge into the deep sea, 10 000 meters below. Sanji, thinking of mermaids, almost faints. Being surrounded by enormous sea creatures, three fishmen come close. Luffy is asked to become a subordinate to the New Fishman Pirates, while Usopp fuels the tank to do Coup de Burst to Fishman Island. The chapter ends with Luffy turning down the offet by saying, "No way, morons!"
