Yea. This isn't exactly a avatar site but Babydow a site that lets you adopt a baby name it and care for it. They start out as a magical garden seed and they grow into a few hour year old baby. A Garden Fairy planted a either rose seed or cabbage seed in your garden! The rose represents a girl. A cabbage represents a boy. And if you don't want to wait that long theres another magical garden seed you can use.
