Mocha

Mocha is a girl who was being held captive on Punk Hazard. She was freed with the rest of the children by the Straw Hat Pirates.

Appearance
Mocha is much larger than an average little girl because of the experiments done to her. She has a large head that is not very proportionate to her body, big dark eyes, and wavy, unkempt, dark hair. She wore a light colored sleeveless dress during her time in the Biscuits Room and a coat outside when Kinemon gave them all warm clothes.

Personality
She is a normal and timid child, as she was scared of Kinemon's severed head. She seems to like Nami, calling her "Big Sis". She was desperate to get out of the Buscuits Room and asked Nami to help the other children.

Punk Hazard Arc
At some point, she was taken from her family after being told she was sick and would be made healthy again. She stayed with the other children in Biscuits Room on Punk Hazard until the Straw Hats broke them out. She was the one who told Nami and Chopper about the corpses in the walk-in freezer. Later, she succumbed to the withdrawal symptoms of NHC10, which she and the other children were fed regularly in candy form. Usopp eventually knocked out the children with sleeping gas, and the Straw Hats chained them all up for safety reasons.
