History
After capturing Usopp and Robin, they took him to the Kingdom of Tontatta. Bomba and some dwarves searched Robin 's body. They released Robin after he promised not to hurt the dwarf. But because he could not give a weapon, the dwarves would confiscate his clothes. The action stopped, after Flapper came to tell him he was a friend of their "hero".
The dwarves asked Usopp to help them fight the Donquixote Family. The group then left for Dressrosa via an underground passageway and arrived at Flower Hill where they met the Thunder Soldier. When the SOP operation began, the group went to the SMILE Factory through a secret tunnel. Arriving at the underground port, Thunder Soldier along with the Kabu team parted ways to go to the royal palace, while others continued their plans to subdue Sugar.
