Uhho-kun is a gorilla.
Uhho is a black gorilla that is much larger than normal humans.
When it was a toy, it resembled a musical chimpanzee toy with cymbals attached to his hands, a frill on his neck, and a conical striped hat.
It took a liking to the Marines' okaki, leading it to follow Sengoku around and carry him when he wished.
Abilities and Powers
When Sengoku and Tsuru arrived with Marine reinforcements three days later, Uhho took a liking to Sengoku's okaki and hung around him. As the Straw Hat Pirates and their allies escaped Dressrosa, Sengoku rode to Fujitora on Uhho's back.
