You can't.
Rather, Eevee is given to you at Celadon Mansion (much like Pokemon Red) and you must trade for or breed to get more Eevee.
no clue. if u figure it out, please post the answer.
Eevee can only evolve into Vaporeon with the use of a Water Stone, Jolteon with the use of a Thunder Stone or Flareon with the use of a Fire Stone in Pokémon FireRed and LeafGreen, it cannot evolve into Espeon or Umbreon because there are no day or night functions in FireRed or LeafGreen.
yes
get a girlfriend
Eevee is not caught. Eevee is an item on a table if you go to Celadon. Go around back to the building with a big door then go up the stairs. Go into the room and pick up the item. EXTRA: If you would like to see the evolutions of Eevee, go to Bill's house North of Cerulean and look at his PC. If you have an eevee and want more you can go to four island and put an eevee and a ditto so it can make an egg and it will hatch into a baby eevee.
Glaceon doesn't exist in firered.
you can by evolving eevee but not by capturing
(firered) get eevee in celadon and give it waterstone.
Evolve Eevee by exposition of a Thunderstone.
no clue. if u figure it out, please post the answer.
the only way to get eevee in diamond or pearl is by trade or you can migrate it from leafgreen and firered. sorry=l
Vaporeon does not naturally appear in the wild in Pokémon FireRed, so you cannot catch them from the wild. However, you can obtain a vaporeon by using a Water Stone on an eevee.
You would need to evolve Eeevee to Espeon with max Happiness during the day. Eevee can be given to you in Celadon Mansion. If you already evolved the given Eevee, you can breed for an Eevee or trade with a friend for an Eevee.
You don't catch one, you go on top of the tower in celadon city and in the room there is a pokeball, pick it up and inside is an eevee
You get an Eevee from a person in Celadon Mansion.
you can get a female eevee as i have got one.
Eevee is not available in Pokémon Sapphire. Eevee is available in Pokémon FireRed and LeafGreen and you may be able to trade it from LeafGreen or FireRed to Sapphire.
