Kumashi is Perona's faithful pet and servant, appearing in the Thriller Bark arc. At some point in time after Hogback met Perona ten years ago prior to current storyline, Hogback created a zombie based on Perona's teddy bear per her request. This zombie was given a person's shadow to animate him and was named Kumashi. He is very loyal to Perona and, while Perona finds him cute, she dislikes his voice, so whenever he tries to speak, Perona will silence him. In the anime, Perona's point is further justified as Kumashi is given a rather uncute voice. Kumashi, however, is always on her side, no matter how strict she is.
