Golduck Are large bipedal ducks, with blue skin and strong, webbed appendages that give them the ability to swim at high speeds. Due to their bluish color and webbed hands and feet, Golduck are sometimes mistaken for Kappa. They have more formidable psychic powers than their Psyduck stage, and they lose the headaches that they constantly suffer from. The gem on their heads glows when they use psychic powers as well as when they swim at full speed. They live in fresh-water lakes and rivers, where they are seen gracefully swimming, especially at dusk. As one of the faster swimming Pokémon, they can out swim even the most athletic of humans, though they often train with swimmers. As they are able to swim in severe storms, they are sometimes found rescuing people lost at sea from danger.
