Long Summary
After activating  Gear Fourth, Luffy  continues to pummel  Katakuri  with multiple Kong Gun attacks, eventually sending the Sweet Commander flying. Luffy proclaims that since Busoshoku Haki makes Logia types take form and it simply passed through Katakuri, he knew that he was not a Logia user. He notes that Katakuri's most notable trait is not his control over his  Mochi Mochi no Mi abilities, but his Kenbunshoku Haki and declares that his Gear Fourth form will not be beaten by him. Katakuri glares at him but is impressed Luffy was able to figure it out and wonders aloud how long it has been since he actually was hit by an opponent. He mentions that if a Kenbunshoku Haki user is not calm or collected, they will be unable to use the ability; he muses that is why Luffy was able to overcome Charlotte Cracker. He then traps Luffy within mochi and lands a direct hit squarely on his chest. Luffy smashes through several walls and is seemingly knocked unconscious; Katakuri bemusedly asks Luffy if he's 'back to square one.'

On Cacao Island, Pound approaches the Sweets Factory and asks to see Chiffon despite the guards insisting that her and Pudding requested no one to enter. Inside, Pudding, Chiffon and Sanji continue  working on the cake when Brulee informs Pudding that the Straw Hat's ship will be arriving at the island at roughly 1am to meet back up with Luffy. She proclaims that Luffy will never beat Katakuri and get there in time and that they will be destroyed by Big Mom during her eating fit.

At the same time, Oven arrives at the island and is curious why no one, not even other members of the Charlotte family are allowed inside; regardless, he heeds the request but gets curious about the commotion outside the factory. He notices Pound and decides to throw him out, despite the latter's pleas. Pudding is worried about Luffy's fate, saying that Katakuri has never lost to anyone; Sanji smiles and states that today he will suffer his first loss.

As the Thousand Sunny continues to journey towards Cacao Island, Nami is curious why no one seems to be pursuing them. Jinbe notes this as well, hoping that Aladine and the other Sun Pirates made it out safely. While Mont-d'Or is informed that Big Mom is attacking Nut Island, he's notified that all the sea slugs have mysteriously disappeared. He incredulously asks what happened to them; it's revealed that Praline had been singing to all the sea slugs, rendering every single one inactive and opening the path for everyone to escape from Totto Land.
