Quadducks were six-limbed avians that could be found on the planet Naboo, in the Mid Rim of the galaxy. They were related to the ducks and the pelikki, two other waterfowl species that also lived on Naboo. In addition to their wings, they had not two but four legs. Despite being bigger than them, the quadducks were preyed upon by the twirrls, a species of flying mammalians.
