A Small Dragon! Momonosuke Appears!

Within the refuse beneath C Building, the creature gives Luffy his name, Momonosuke, snapping at him for drooling and insisting he is no meal. At first Luffy takes him for an eel before realizing the dragon itself is the one speaking. The young dragon recounts stowing away aboard a boat to reach the island knowing little about it, keeping apart from the other children, and refusing Caesar's candy for days until hunger pushed him to swallow a Devil Fruit. A girl caught him mid-transformation, and the soldiers afterward identified the fruit as Vegapunk's failed artificial creation.

Momonosuke insists he is truly human and is startled when Luffy notes that a fruit eater can revert, though Luffy admits he himself is no Zoan. Determined to leave, the dragon shares that he overheard Caesar predict every child would die within five years, and he regrets falling into the hole before he could warn them. The admission lights a fire in Luffy, who vows to scale the walls alongside him, and a sudden vision of Doflamingo so terrifies Momonosuke that he takes flight with Luffy clinging on. Meanwhile Usopp, Brook, and Kin'emon hunt for Seastone handcuffs while Brook peers behind walls with his powers. On an upper floor, Monet conjures a blizzard and stabs Robin, so Zoro steps up to handle the Logia user, twenty minutes before the gas overtakes B Building.

The episode carries a rating around 7.6. Its small quirks include an animation slip in which Momonosuke's mouth stays closed in a reflection but open in the actual shot, and padded footage stretching out the ongoing clash between Vergo and Smoker.
