Question: is eevee in fire red?
Answer: In Celadon City, you can go out through a gap in the trees on the north side of the city, which gives you a way to enter the Celadon Mansion from the back. On the top floor, there is a room with an Eevee in a Poké ball on a table. If you want more Eevees you must breed it with a Ditto at the day care on Four Island.
