Clefairy volunteered to battle Koga when he saw that he stole some Chansey from a juggler. He went up against Koffing first and had trouble with its gases. Clefairy countered it with his own gas and waved a fan to make the figure made out of gas to look real, and took out Koffing. Grimer was next and one touch from it made Clefairy to wash himself off as Grimer was dirty and he did the same to it. Clefairy then placed Grimer in a washing machine but it escaped. As Clefairy was cornered, the Chansey that were trapped broke themselves free and saved Clefairy. After Pikachu rescued their eggs that were stolen by a Chansey torturer, Clefairy was baking them as he became hungry and the Chansey smacked him with a wooden pillar for doing so.
