Das gigantische Monster Smiley spuckt unaufhörlich seine Einzelteile über den See. Einige Tropfen landen im See und vergiften ihn. Sanji entschließt sich, den Samurai-Torso im See zu bergen. (Text: ProSieben MAXX)
Sanji, Kin'emon, Brook and Zoro see Smiley. Brook talks about a story about slime eating the clothes off of women making everyone act perverted except for Zoro, who points out that the slime is killing the fish in the lake, prompting Sanji to jump in to find Kin'emon's torso. Law tells Monet to take a walk with him while Chopper is left in the lab to find the antidote. Luffy faces off against Caesar who uses his Gas Robe attack until he discovers that Luffy is immune to poison. Caesar then uses his Gastanets and Smiley to injure Luffy who then grabs Caesar. Caesar then knocks Luffy out with an unknown ability. Robin, Franky, Tashigi and Smoker get knocked out as well. Law and Monet are walking down a hallway and encounter a mysterious figure who causes Law to break down in pain while the mysterious figure tells him that it's been a long time since they last met.
Zoro si accorge che i frammenti di Smiley stanno intossicando il lago: Sanji, deciso ad evitare che il torso del samurai patisca questa fine, si tuffa per recuperarlo; nel frattempo Law, come stabilito, porta Mone fuori dal laboratorio, lasciandovi Chopper nascosto in una borsa in modo che possa compiere la sua ricerca sulla droga NCH 10. Rufy e Caesar cominciano a combattere, e quando il ragazzo sembra avere la meglio, improvvisamente Caesar si rialza e Rufy crolla a terra, così come Robin, Tashigi, Franky e Smoker. Law intanto, avverte all'improvviso un forte dolore al cuore: la persona che sembra provocarlo si fa avanti salutandolo e dicendo di trovarlo cresciuto.
El monstruo Smiley sigue enviando trozos de si mismo al otro lado de la isla con la intención de cruzar así el lago. Mientras, Luffy inicia una batalla contra Caesar y sus poderes de la fruta gas-gas.
Al lado del lago de hielo, Sanji se tira al agua para rescatar el torso del samurai antes de que el veneno de los Smileys que caen al agua lo maten.
La violenta batalla entre Luffy y Caesar da un giro inesperado cuando misteriosamente Luffy cae inconsciente.
