Golduck

Golduck is the final evolved state of the headache-plagued Psyduck. A Golduck has not yet been seen in the wild by Ash, or any other Pokemon trainers for that matter, so no true information is available on these creatures. The Pokemon has this to say about this water Pokemon: Golduck is often seen swimming elegantly by a lake shore.

First appearance: Ash has not yet encountered a Golduck
