Caribou's Kehihihihi in the New World Final - "Thank you Pirate Caribou, Who is as Sweet as my Grandson".

Short Summary
Bellamy, who lies badly injured, is saved from Dellinger by Bartolomeo until the Doflamingo pirate left due to a change in his orders, leaving Bellamy in Bartolomeo's hands.

At the flower field, Thunder soldier reveals the name of the operation and explained the layout of the secret underground factories and trade port as well as the toy slaves and the dwarves held underground. He also reveals the identity of the fruit user responsible for turning people into toys and the frightning nature of her powers. He believes that the defeat of the girl Sugar would undo everything caused by her.

In the Colosseum, Luffy manages to find Bartolomeo and Bellamy during his search for an exit. Though Luffy was reluctant to leave the Mera Mera no Mi he has no choice since the lives of his crew are on the line. Fortunately, Bartolomeo agrees to obtain the devil fruit for Luffy. But then, a stranger appears and tells Luffy that the Devil Fruit cannot be given to him, earning him the irk of Bartolomeo but easily brushes him aside as he approaches Luffy who looked at him in tears.

At the center of the colosseum, Acilia has teamed up with Rebecca to ensure her chance to reach the finals. Meanwhile, outside the colosseum, Luffy manages to escape with Zoro and Kin'emon who disguised themselves as toy fish. Zoro questions Luffy about why is he still crying, but Luffy says that everything is alright.

Elsewhere, in the middle of an alley, a young woman named Koala is talking with the stranger who met Luffy, who is doning Luffy's colosseum disguise and told her that he must get Ace's devil fruit back. Luffy was still reeling from the fact that the stranger he met was someone he thought was dead a long time ago.
