Some Native Americans in the Southwestern United States believe in a fertility god called Kokopelli who is in charge of childbirth and agriculture (the growing of plants and animals for food and other uses). He also plays tricks and is a symbol for the spirit of music. Kokopelli is sometimes shown as a man playing a flute with a humpback (a back that is bent forwards), things like feathers sticking out from his head, and a very big penis.
