Short Summary
Katakuri prepares to hunt down the Sanji Retrieval Team himself, but the Big Mom Pirates are suddenly approached by Big Mom, who is on a rampage induced by a craving for wedding cake. Perospero lies that the Straw Hats have a second wedding cake with them, and Big Mom hunts them down; Pudding then reveals that she can make a wedding cake on Cacao Island if she forces Chiffon to help her. Meanwhile, the Sanji Retrieval Team finds a newly resurrected King Baum and forces him to carry them off the island, but Big Mom suddenly flies in on Zeus and prepares to attack them.

Long Summary
The citizens of Sweet City help each other recover from the wreckage caused by the toppling of the Whole Cake Chateau, and an appalled Count Niwatori asks his crewmates what happened. They reveal that the wedding ceremony and wedding cake was ruined, their plan to assassinate the Vinsmoke Family was sabotaged, and Bege had attempted to assassinate Big Mom. Niwatori was angered to hear of Bege's betrayal, and Compote wonders what could have possibly caused the explosion that toppled the Chateau. No one can think of an answer, but Niwatori reveals another piece of information: that communications were cut off to the tea party venue. Oven asks what needed to be communicated, and as Niwatori prepares to answer, Pekoms comes in and reveals that the Sun Pirates all ran away. The two then find out that Jinbe left the crew to join the Straw Hats during the tea party, and Daifuku reports to Katakuri that they have squads going after the Straw Hats, the Fire Tank Pirates, and the Germa. Katakuri tells Brûlée to come with him, and Brûlée is ecstatic that he is going to take out Luffy himself before the Straw Hat can become a serious threat to Big Mom.

Suddenly, Smoothie comes running up to her crewmates and tells them to get away from Sweet City, as she is pursued by Big Mom, whose eating disorder has manifested and caused her to go on a rampage for wedding cake. In Big Mom's hand is a dead Opera, which shocks the Big Mom Pirates, who know that standing up to Big Mom in this state is suicide. Smoothie desperately asks for Streusen, but it is revealed that Streusen took a hard fall while saving everyone and will take some time to recover. As the Big Mom Pirates get more and more frightened, Perospero lies to Big Mom that they made a spare cake, but the Straw Hats stole it. He reveals where the Straw Hats currently are, and the crew hopes that Big Mom will hear him; she does, but threatens to kill him should she find out he lied. She then summons Zeus and jumps on him, flying towards the Straw Hats focused solely on getting wedding cake. The Big Mom Pirates are relieved but still stressed, especially Perospero, who knows that it will take days to make a good wedding cake, and that they lack the ingredients they had stolen from other islands. However, Pudding arrives atop Rabiyan and reveals that she can make a chocolate chiffon cake on Cacao Island, as her skills as a chocolatier rival Streusen's skills as a chef. She knows that she can make the cake especially well with Chiffon's help, and her crewmates point out that Chiffon is currently affiliated with Bege, but Pudding says she can get her half-sister to help her as she brings out her Walker and her third eye is uncovered, creating an aura that strikes fear into the citizens. Pudding says she has all the ingredients at Cacao Island, including some reserve ingredients from other islands, and tells her crewmates to direct Big Mom to the island after she has vanquished the Straw Hats. She wishes to repay Big Mom for killing Sanji after the Straw Hat cook disgraced her.

Meanwhile, Nami tells her crewmates to hurry up, which annoys Luffy, as she is riding on Jinbe's shoulders. The team approaches the Seducing Woods, and is hesitant about going back in there, but Nami suddenly sees King Baum, who has been resurrected with his sides sewn together and is currently romancing a female tree homie. Nami calls out to King Baum, and the team rides on him once again, much to his bitter anger, as Nami had cut Lola's Vivre Card and still has one half after the other was taken. With King Baum, the team is confident they can cut through the Seducing Woods, though they notice that the Big Mom Pirates are pursuing them. Nami forces King Baum to go faster, but Big Mom suddenly comes flying in at that moment, and she bears down on the Straw Hats in a mad rage, telling them to hand over her cake as she wields Napoleon in its sword form.
