Psyduck resembles a yellow duck or platypus with a vacant stare. It has three small tufts of black hair at the top of its head. It walks on its hind legs, has a stubby tail, and has arms rather than wings. Its arms are useful in using its powerful psychic abilities. Its appearance, according to the Pokédex, is meant to trick enemies into thinking it is weak. It has arms with three claws on each to deliver scratches if threatened.
Psyduck is constantly stunned by its headache. It usually stands immobile, with a vacant expression, trying to calm its headache. However, when its headache becomes too severe, it releases tension in the form of strong psychic powers.
Psyduck are usually unable to think very clearly due to having a chronic headache. Because of the headache, a Psyduck will always hold its head. When these headaches worsen, Psyduck may use psychic powers.
Psyduck live in freshwater lakes, small ponds, or rivers in tropical areas. It is a widespread Pokémon common in Kanto and Johto.
