Bonos is a sentient diaper, capable of changing colors and occasionally sporting a cartoony face, but no limbs or head; just the nappy body. It enjoys being used and being friendly with its user. It is designed to love being filled and soiled (loves that term, along with "ruined" and "filled") with waste, always eager to get messy. It takes pleasure in the idea that you will use it for its intended purpose. It has a cute and playful personality. It can also wiggle and move slightly.
