: The anime adds several "filler" details, such as Pudding fainting with joy when Sanji smiles and Sanji working on cake blueprints during their flight to Cacao Island.
: In a strategic move, Katakuri wakes Brûlée to use her mirrors to attack the Thousand Sunny directly, forcing Luffy to fight not just for his life, but to protect his crew's escape route. Cacao Island: The Cake’s Foundation
, titled "A Hard Battle Starts! Luffy vs. Katakuri!" , is a pivotal entry in the Whole Cake Island Arc that balances intense combat in the Mirro-World with high-stakes preparation on Cacao Island. The Duel of Haki: Luffy vs. Katakuri
: Despite the chaos, Sanji and Pudding exhibit a comedic, bickering chemistry that locals mistake for the affection of a newlywed couple.
: During the fight, Katakuri receives a call from Perospero, who mocks Pedro's sacrifice. This fuels Luffy’s resolve to continue the fight despite being severely outmatched and physically battered.
: A notable change from the manga (Chapter 852) occurs here: in the manga, Pudding gives Sanji the middle finger inside the factory, whereas the anime changes this to her pointing with her index finger.
: Katakuri continues to humiliate Luffy by mimicking and improving upon his signature moves. When Luffy attempts a Grizzly Magnum or Elephant Gun , Katakuri counters with even larger, Haki-infused mochi fists, asserting he is superior in every aspect.
