At the Thousand Sunny, Big mom asks where the cake is. Jinbe tells her that it is not on the ship, but Big Mom disagrees, saying that her son would not lie and if he did, she would have to kill him. Perospero panics as he realizes she has remembered. Big Mom then uses her Cognac attack. Jinbe blocks the attack for a while before he is sent flying. Big Mom attacks the ship, and Nami notices she is destroying the room that Carrot is in. She tries to stop Big Mom, but she attacks her. Luckily, Chopper stops her with Guard Point, and Big Mom states that she will add Chopper and Brook to her collection after she has eaten. The sail catches fire from Prometheus. Jinbe returns and puts out the fire with a sea current. He then hits Big Mom in the stomach with a Fishman Karate move, knocking her off the ship but Zeus saves her. Jinbe orders the crew to speed up, but Big Mom catches up again and Nami tries to tempt Zeus. Zeus is briefly enticed but then shouts at her saying that the same trick will not work twice before trying to electrocute her. Chopper cries out and then Brook walks out of the lightning, saying that he does not have any flesh so it does not affect him. He then asks to see Big Mom's panties, and everybody looks shocked.
