Introduction
A shyboy loves balloons. He is rich in emotions, but he doesn't know how to express and that makes him looks expressionless.
Cocoa joined the Pumpers where he believed he can make friends. He cannot speak well, so others can hardly know what he wants to say. His best friends, Yajin and Pyrope, can understand his thinking, fortunately.
Cocoa enjoys all about balloons. He loves the feeling of floating in the air most. He's not afraid of popping, but he gets surpised if he's not ready for it.
