Rosario

Rosario was the giant pet goldfish of Muchigoro in the sixth One Piece movie.

Appearance
Rosario is a giant red fish with a hard metallic shell. The shell has jewels embedded on the top part and on the forehead.

Personality
Little is known about Rosario’s personality, but he seems intelligent enough to follow Muchigoro’s orders.

History
When the Straw Hat Pirates participated in the first Trial of Hell issued by the Baron Omatsuri, they were initially tricked into thinking they had to catch small goldfish, but eventually caught her due to Chopper's Guard Point.

Trivia

 * "Rosário" is Spanish, Portuguese and Italian word for "rosary".
 * Despite all the revived Red Arrows Pirates having sprouts on their heads, Rosario does not. Since Baron Omasturi states that all his crew was killed before he used Lily to revive them, Rosario was probably not used by Muchigoro when he was alive.
