Shaking Up the New World! Caesar's Horrendous Experiment!

Caesar herds the children back inside, dangling the candy waiting in the Biscuits Room, but Mocha begins resisting the addictive drug as recollections of the lab's cruelty flood her mind. She understands that Nami and Usopp had been working to free everyone, and she fights to get away, crying out for them. At the faraway hideout, Nami comes to, stunned that Sanji's borrowed frame carried her through Caesar's strike, then moves to rouse Usopp, who grumbles his letdown on finding it is only her.

Rejoining Vergo and Monet, Caesar discloses that Monet's tracking laid bare every move in Law's plot, and he thanks the doctor for foolishly surrendering his own heart through their pact. When Law jabs at his intelligence, Caesar wrenches the heart from Vergo's hand and drives a fist into it, leaving Law unconscious. He then opens a feed to the brokers, retelling Smiley's past and announcing that the formerly flawed weapon, once fed a prepared bait, will turn into the deadlier Shinokuni.

Mocha resists the candy's pull and realizes the Straw Hats had meant to save the children. Back at the shelter, both Nami and Usopp regain their senses. Caesar admits he has quietly traced Law's plans by way of Monet's powers, then tortures the captive by squeezing and punching the heart Vergo holds out. Over the broadcast he lays out Smiley's origin and the improved Shinokuni for the watching brokers. Out in the snow, the still-growing Smiley disregards Caesar's orders and gulps the giant bait candy down whole, leaving the audience baffled by the creature's odd behavior.

Belonging to the Punk Hazard Arc, the episode debuts Dragon Number Twenty-One, one of Vegapunk's artificial dragons. Anime-only additions have Mocha hallucinate frog-headed and lizard-headed figures beside the snake-headed one, depict Monet pouring Vergo coffee and asking about milk, and show Caesar clutching the same acid bottle used to wreck his men's sled while feigning concern for them. Notably, the trailer for the next installment was trimmed for the first occasion stretching all the way back to Episode 579.
