Uhho

Uhho is a gorilla who appears in the Dressrosa arc of One Piece. He had been turned into a toy by Sugar years earlier and, after being freed, became a devoted companion to the Marine Sengoku.

Uhho is a black gorilla noticeably larger than an average human. While transformed into a toy, he resembled a wind-up musical chimpanzee with cymbals on his hands, a ruffled collar, and a striped cone-shaped hat.

Uhho was turned into a toy sometime within the decade before the Dressrosa arc by Sugar, whose Devil Fruit power can transform living beings into toys. He remained trapped in that form, watching over the Corrida Colosseum, until Sugar was knocked unconscious.

Uhho reverted to his true gorilla form the moment Sugar was knocked out, since her toy transformations undo when she loses consciousness. His return to full size was so sudden and powerful that it cracked the seating of the Corrida Colosseum.

Uhho grew fond of the Marines' okaki crackers, which Sengoku fed him, and this attachment led the gorilla to trail after Sengoku and carry him wherever he wished. He eventually carried Sengoku over to Fujitora as the Straw Hats and their allies slipped away from Dressrosa.
