Muchigoro is a revived crewman of the Red Arrows Pirates who appears in the sixth One Piece film, Baron Omatsuri and the Secret Island. Gullible and tearful, he challenges the Straw Hats in a goldfish catching contest.
A sprout pokes from the top of Muchigoro's head, the telltale mark shared by every Red Arrows pirate brought back through Lily Carnation's power; otherwise he looks exactly as he did in life. His mouth is oversized in the manner of Usopp, and his rounded torso paired with short legs recalls Foxy. Fish-like touches finish the design: webbing between his fingers and skin marked with spots and patterns. For clothing he keeps a black coat open over a bare chest and pairs it with shorts. Frail as his frame seems, he stayed upright through a massive wave conjured by Rosario without budging.
Sharp thinking is not Muchigoro's strength. He swallows Usopp's tall tales completely, even weeping over them, and flies into a tantrum the moment anyone mangles his name, settling only once his captain orders him to behave. His affection runs deep for both his crewmates and his pet goldfish Rosario, and he loses his temper when Zoro reaches for his blades near her or when Sanji kicks her. That same trusting nature makes him an easy target for Robin and Nami, who ply him with drink and flattery and draw secrets out of him without his ever noticing the manipulation.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
Long ago Muchigoro signed on with the Red Arrows Pirates, who roamed the Grand Line during Gol D. Roger's era. A devastating storm wiped out the whole crew and stranded their captain Omatsuri alone on Omatsuri Island, where he later found the Lily Carnation and used it to resurrect his fallen men. The revived pirates spent their days luring crews to the island to splinter them and feed the flower. When the Straw Hats arrive, Muchigoro runs the first Trial of Hell, a contest to net his giant goldfish Rosario. He nearly bags her with his paper net, but Robin blocks the catch and Chopper finally knocks the fish into the bucket using Guard Point, handing Muchigoro his defeat. Bound by the island rule to obey the trial's winners, he waits on Robin, then drinks himself loose enough to reveal the flower's name and the crew's link to Roger's time. He withers when the flower is fed, briefly returns, and turns back into root once Lily dies, telling the dying Omatsuri from the afterlife that he ought to have sought new crewmates.
