Cilan's Stunfisk lived together with Ash's Palpitoad in a lake near Raimon City. They were very protective of trespassers in their lake and Stunfisk used Discharge on Ash Ketchum and Ash's Oshawott to get them out of the lake. Cilan decided to get out his fishing rod to keep it occupied while Ash Ketchum and Ash's Oshawott battled the Palpitoad. Cilan ended up swinging the Stunfisk on the ground to knock it out and then caught it.
