She caught it by accidentally dropping her Poké Ball and Psyduck touching the button. Although it can sometimes annoy Misty, she and Psyduck have a good bond and Misty refused to trade it for any Pokémon no matter what.
In one episode it was close to evolving and thought to have evolved into a Golduck, but it was later revealed to be a wild Golduck that liked to impress girls. In the same episode it was revealed that it could not swim.
