Eevee evolves into Umbreon (the pokemon you want) or Espeon when it is evolved in day or nighttime. Unfortunately, since Pokemon Leafgreen lacks an internal clock, you must trade your Eevee to Emerald/Sapphire/Ruby or later and let it evolve at night in order to obtain Umbreon. The daytime refers to the hours of 12:00 AM to 12:00 PM, and the nighttime refers to 12:00 PM to 12:00 AM. Have fun.
Well no but u can get a code to turn ur trainer into him
It does not evolve with a dusk stone in Pokemon Platinum
u cant
you have to turn bill back into a human then he will give it to you.
Trade an Eevee and have it traded back. Get out of the Union room and save your game, and turn it off, then on. Check out your ex-Eevee, because it's now a Stareon.
In Pokemon Crystal, a player can obtain an Umbreon if they already have an Eevee. The Eevee must reach maximum happiness and be leveled up at night for it to evolve into an Umbreon. If it evolves during the day, it will turn into an Espeon.
well, the only one I know about is eevee, whitch a waterstone will turn it into vaporeon.
you go to two island and board the fairy and turn it off as you are in the black.
you save before you fight and if you kill it just turn it off and back on
Give the fossil to the guy, walk out, and immediately walk back in. It's instantaneous.
You have to evolve it from Eevee. If there is a thunderstone in that game, use the thunderstone and Eevee will turn into Jolteon. If there is no thunderstone, then you must evolve Eevee by training it, but it might turn into Flareon or whatever the water pokemon's name is that it turns into. You can also trade it with yourself to a game that has a thunderstone and evolve Eevee that way, then trade it back.
eevee evolves through different stones depending which Pokemon you want, fire water or thunder stone all work EDIT:and if you level it up with high enough freind ship between 4am and 8pm it will turn into espeon and if you level it up with a high enough freind ship between 8 pm and 4 am it will turn evole into umbreon dark espeon psychic :)
