Summary:
Caesar Clown and the children are seen exiting a flying gas balloon, surprising the nearby marines who ask what kind of ship it is. Caesar enters the research lab through the upper entrance and reminds the kids that the lab is their home and their sweets are in the Biscuits Room. Ordering their subordinates to lock the door to make sure they don’t escape again, all the kids eagerly rush inside, except for Mocha, who begins to resist the addictive drug upon entering and recalls her horrifying memories of the Lab. Some of the satyrs try to calm her down, but she finally remembers Nami and Usopp telling all the kids not to follow Caesar and trying to save them. Realizing exactly what happened, she starts trying to escape again, yelling for Nami and Usopp to help her.
Far away, in the Straw Hats’ makeshift hideout, Nami finally regains consciousness and marvels at how Sanji’s strong body allowed her to survive Caesar’s attack. Noticing Usopp starting to wake up nearby, she moves to help him. Usopp mistakes her for the real Sanji, and let’s skip his disappointment that it’s actually Nami that caused her to become somewhat rough.
Back at the lab, Caesar meets Monet and Vergo, the latter talking about how they just had coffee with some cookies, only to quickly remember that there were no cookies. The mad scientist asks Caesar when he will start the experiment and asks Monet to gather some pictures, and tells Verga to do a better job of keeping the marines at bay, admitting that the arrival of Smoker and his men caused him. to be nervous.
Moving to the cage, Caesar reveals that he knows all of Law’s plans due to Monet’s tracking of Law with her powers and thanks Law for naively giving him his heart in exchange for Monet’s heart as part of their deal. Caesar reacts to Caesar’s condescending joy by insulting his intellectual abilities, becoming enraged and grabbing Law’s heart (which was held by Verg) and squeezing it, causing Shichibukai pain. Amazed and shocked at how he can still survive despite his heart no longer being in his body, Luffy is interrupted by Smoker who demands to know where his heart is currently being held. Caesar held it out in front of him and taunted him mischievously about it.
Caesar takes a call from his subordinates and then proceeds to broadcast to the brokers via Den Den Mushi, explaining the nature of his pet/weapon Smiley and the history of the island. He pinpoints the weapon’s only flaw from four years ago and explains that he has since removed that flaw, and by feeding Smiley a special bait he prepared, the poisonous axolotl became an enhanced weapon called the Shinokuni; is an even more powerful poison gas weapon than before.
Outside in the winter area, Smiley is shown still stalking Sanji, Zoro, Brook, and Kin’emon, who marvel at his ever-increasing size. In the distance they notice a giant candy with a large screen behind it and something below it. Dragging candy across the plains, several of Caesar’s underlings and Vegapunk’s dragon then ask Caesar to run before Smiley catches up with them. Realizing that their sled was no longer usable, they quickly fled with the Straw Hats and Kin’emon trailing briefly as the dragon broke free. When Smiley reached the candy, he paused briefly after seeing Caesar on the display. Attempting to demonstrate his taming of the monster, Caesar began to issue orders for the slime to be ignored, with the monster quickly devouring the large sweet.
