Koduck

Koduck is a yellow Pokmon resembling a duck or bipedal platypus. On top of its head are three thick strands of black hair and it has a wide flat creamcolored beak. Its eyes seem vacant and have tiny pupils. Its legs and tail are stubby and it has creamcolored webbed feet. There are three claws on each of its hands. Koduck is constantly stunned by its headache and is unable to think very clearly. It usually stands immobile trying to calm its headache. However when its headache becomes too severe it releases tension in the form of strong psychic powers. The use of these powers produces brain waves identical to those seen in sleepers and the Pokmon is unable to recall these episodes. Source: Bulbapedia
