In the anime, Misty has a Psyduck that she accidentally caught in "Hypno's Naptime". It is a constant source of frustration for her, as it frequently emerges to attempt to battle the opponent in substitution of the Pokémon she intends to use, and in instances where she does intend to use it, it will more often than not goof up (most notably in the episode "Snack Attack!"). Despite this, she has been shown to deeply care for it. Despite being generally shown as dimwitted and oblivious, when its headache gets bad enough, it has been shown to use phenomenally powerful Psychic-type moves which far exceed its perceived potential. It is also shown to be unable to swim, despite being a Water-type Pokémon. Nine Psyduck appeared in "The Psyduck Stops Here!"; six parents and three babies. Three of the parents were blocking the path that Ash and his friends tried to pass on their way to Celestic Town. The Psyduck weren't able to return to their real home, Lake Psyduck, because of three Muk.
