Manboshi

Manboshi is a moonfish merman and the third son of the royal Neptune family on Fishman Island.

Appearance
Manboshi is a rotund, stocky merman. Like his brothers, he has a polka dot tail. He wears a hat with a white stripe going across the middle of it. The stripe is serrated on the bottom side and there is a dot pattern inside the stripe. He also wears a sash, like his two older brothers.

Personality
Manboshi is perhaps the most energetic among his brothers. He talks in song, and has a habit of saying "Akkamanbo". It appears he can be rather unpredictable, as he asked Ryuboshi to dance with him in the middle of looking for the Strawhats. Like Ryuboshi, he sings when he talks, except he doesn't sing in scale.

Abilities and Powers
As a prince, he has some royal authority granted to him. Unlike his brothers, he has not displayed any fighting abilitis nor has he been shown using a weapon. Hammond described Manboshi and his brothers as the three most powerful members of the Neptune Army, implying he has great fighting prowess.

History
He and his two older brothers, Fukaboshi and Ryuboshi, were first seen when they went to Mermaid Cove, investigating the illegal entry. At one point he yelled for everyone to start dancing. He is currently still at Mermaid Cove after the Strawhats took the royal gondola.

Trivia

 * His name is a pun on Akamanbō (moonfish) and Mambo.
