You helped Camie rescue the Strawhats, which was only Luffy, Sanji, Usopp, and Chopper. Luffy was the last one to wake up. After they were all awake, Camie took them to the surface and took them to the mermaid café. Sanji only simped and was trying to get with every woman he sees. Luffy was amazed by all the mermaids, he hasn't seen other mermaids other than Granny Kokoro, and Camie.
