This tiny bunny has a somewhat unusual name. Her first human was a young violin player, and this human thought that Robin would be a very pretty name for such a gentle-looking bunny. However, the human had a relative named Robin, and therefore the name was already taken. In a flash of inspiration, she thought about rosin, which is the sticky stuff violin players rub on their bow hairs, and realized it would be just as pretty of a name. Rosin the bunny does not play violin, but she thinks she might be interested in trying out clarinet.
