Eevee in Red, Blue and Yellow
I made a page on Eevee in Diamond and Pearl, but in Red, Blue and Yellow, Eevee’s a bit different. Eevee can only evolve into the first 3 evolutions, Vaporeon, Jolteon, and Flareon, while the other evolutions came in later games.
To get Eevee in Red, Blue, and Yellow Versions, you need to go to the Celadon Mansion, in Celadon City. You have to go in the back way, though; you can’t get to Eevee from the front entrance. Go inside, and keep going up the stairs until you get to the top. There’ll be a man standing there telling you about stuff in the game, claiming he knows about everything in your Game Boy. On the table will be Eevee!
To evolve Eevee, you’ll need a Water Stone, Fire Stone, or Thunderstone. If you don’t have any of these stones, you can buy all of the stones for $2100 on the 4th floor of the Celadon Department Store. Keep in mind that you only get one Eevee in Red, Blue, and Yellow, so make sure you evolve your Eevee into something you really want!
Enjoy your Eevee!
