While teaching Robin how to perform a successful tsukkomi, Usopp is swept aboard a Marine ship and brought to a top-ranking meeting with Fleet Admiral Sakazuki and other high-ranking Marines. After displaying his aptitude for tsukkomi and getting promoted all the way to Admiral, with the moniker "Golden Pegasus", he is revealed to be a pirate by Smoker and is chased out of New Marineford, with Koby replacing him as the "God of tsukkomi".
Two Gold Balls
The Straw Hat Pirates win a lottery, allowing them and Law an all-expenses paid visit to Kyuka Island, guided by Moda. They are ambushed by remnants of Baroque Works, but are saved by Dorry and Brogy, who also won the lottery.
After being thrown to Kuraigana Island by Bartholomew Kuma, Zoro asks Dracule Mihawk to train him as a swordsman disciple. Stalling for time, Mihawk makes Zoro perform a set of menial tasks, which Zoro misunderstands to be indirect training.
The Straw Hat Pirates receive a map and a key to an island called Kuma, also known as Treasure Island, which supposedly houses the legendary treasure "Fabulous Marvelous". They set out towards the island, fighting their way through Crocodile and sets of Marines to obtain the three other keys and, after solving a puzzle only they can solve, manage to open the treasure chest. However, instead of the "Fabulous Marvelous", they find a group of Okama who have been trying to track down Sanji since he left the Kamabakka Kingdom.
Luffy and Zoro
Luffy and Zoro get ambushed by Marines while buying supplies, and after falling down a mountain, end up handcuffed together with Seastone handcuffs. It's revealed that they have been trapped by Monet and Vergo, and they try to fight them off with the help of Rebecca. Bartolomeo and Cavendish arrive as backup as well, but end up handcuffed to the Straw Hat duo as well. Eventually, Rebecca is able to use her Backwater Sword Dance to throw Monet into the ocean, weakening her and allowing Rebecca to take the handcuffs' key and open them. Luffy quickly deals with Vergo, and they return home.
