Summary:
On Broc Coli Island, Sanji’s two older brothers end a two-year war in four hours. They then prepare for a two-day cruise to Whole Cake Island to attend their brother’s wedding.
Meanwhile, the Sanji Retrieval Team sails through Totto Land, admiring the sweet scenery of the archipelago. However, they are attacked by two giant centipedes, but Luffy manages to defeat them both. The team becomes suspicious of Pedro’s advanced knowledge of the area, and he reveals that he has been here once before.
Meanwhile, Big Mom gets a taste for croquembouche, causing her to go berserk, leaving a path of destruction in her wake as she searches for the treat. The Ministers panic when they enter Sweet City and order the citizens to evacuate while Big Mom mindlessly destroys the city.
On the island of Broc Coli, the Germy 66 soldiers enter the battle, where they easily overpower the weaker and less equipped soldiers on the other side. As the massacre continues, one survivor attempts to avenge his wife and children by shooting one of Germa’s commanders. However, the commander lets one of his soldiers take the bullet and confronts the man as he puts the gun to his head. The commander angrily states that the man is holding him up for his brother’s wedding and shoots the man before leaving, winning the battle easily. He then contacts his brother, who collects payment for Germa’s services from the winning party, and the winning party celebrates Germa and their victory. However, once the two brothers are reunited, they taunt both factions that it took two years to fight this war. Overlooking the devastation on the island, they contact someone to inform them that they are taking a two-day cruise to Whole Cake Island. The older brother expresses his excitement to see Sanji again, but the younger one calls him a liar.
Meanwhile, the Sanji Retrieval Team approaches Jam Island on their way to Whole Cake Island, and despite Chopper and Carrot’s wishes to eat more candy, Nami forces them to avoid the coast to avoid detection and continue on their secret journey. They then come to a purple-colored part of the ocean, and Pedro reveals that juice from a nearby island is flowing into it. The team wonders how he knows so much about the area, remembering how someone on Cocoa Island knew him, and becomes suspicious. Pedro then says he’s been here before. Suddenly, the ship is shaken several times by a giant sea centipede, which Pedro claims will eat anything indiscriminately. Centipede emerges and confronts the team, towering over them and the Thousand Sunny. Nami and Chopper get extremely scared, but Luffy, Brook, Pedro and Carrot excitedly prepare for the fight. However, Luffy manages to take him down himself using the Gomu Gomu no Gatling, shattering his shell and sending it back into the ocean. Before the team can recover, they are soon confronted by another centipede that is bigger and stronger than the previous one and withstands Luffy’s Gatling attack. Brook, Pedro, and Carrot try to step in and slice open his chest, but Luffy ends up taking him down again himself when he kicks him in the face with Gear 2. The team sails on peacefully, though Brook, Pedro, and Carrot are none too pleased that it has no chance to attack any of the centipedes. Luffy wonders if they can eat them, but is quickly dissuaded by Nami and Chopper.
Meanwhile, on Whole Cake Island, Big Mom is rampaging through the woods after developing a craving for croquembouche. Her eyes turn red and she is completely focused on getting the croquembouche, attacking anything that gets in her way. She approaches Sweet City with a path of destruction and in Sweet City her ministers panic as they desperately try to appease her eating disorder by getting her croquembouche before she can enter the city. However, all the kitchens are very busy and the ministers are forced to evacuate everyone from Sweet City when Big Mom enters, destroying and eating buildings as she tries to fulfill her desire. A talking cloud and a talking sun try to talk her out of it, but she brushes them aside as her destruction continues. As the citizens evacuate, one person keeps them moving, desperately wondering where the croquembouche is. However, the ministers can only wait in fear for it to come as Big Mom climbs a large building, destroys it and sends the citizens fleeing in terror.
