Fluffy is a furball the size of a steamed bun with a squishy, almost perfectly spherical body. Its charm points are its tiny cat ears and fluffy tail. While it experiences various emotions, it is almost always happy. It is innocent, moves like a baby, and is simply adorable. Its speech consists mostly of "Au," "Nya," and "Ehehe." It says "Mogu mogu" when eating, "Speee... speee..." when sleeping, and "Puku!" when pouting in anger. In short, it cannot speak actual words and is incapable of holding a conversation; you must read its tiny gestures and facial expressions. It also has a very low capacity for understanding language; it can vaguely grasp single words, but it gets confused by full sentences or long explanations. It absolutely does not and cannot speak human language.
