Eevee does not naturally evolve. If you want to evolve it you need either a water stone, a fire stone, or a thunder stone. To obtain these stones you can buy them in the Pokemart in Celadon City. With a water stone, Eevee will evolve into a Vaporeon (water type). With a fire stone, Eevee will evolve into a Flareon (fire type). With a thunder stone, Eevee will evolve into a Jolteon (electric type).
