get the national dex
you have to train or talk to them. well only you can talk in soulsilver or heartgold. i have played .
if you get Pokemon platinum or diamond, then after you beat the Pokemon league, go to the trophy garden on route 212 and talk to the owner. everyday, there is a rare Pokemon in the garden, eevee being one of them.
You must get a National Pokedex first , then go to hearthome city and talk to Bebe. Her house is next to the Pokemon center.
after you get the national dex gon to hearthome city go in the house next to the Pokemon centre and talk to the girl in their and volla!
You can get an eevee if you go up to the man who is outside professor rowens lab and talk to him he will then say My friend is ... and he will tell you where to go you talk to the lady and make sure you only have 5 Pokemon in your handthingy she will ask you if you would like the eevee.
Do get an eevee, or any other trophy garden poke, save in front of Backlot. Then talk to him, and he should go on about his garden, and how it should make you envious. He'll then mention a pokemon, which will be that day's garden pokemon. If it's not the one you want, simply press L+R+start+select to soft-reset, or simply turn your DS then on again, then talk to him again. Repeat until he mentions eevee.
You can't. You have to get NationalDex and then talk to Bebe. She will give you a free eevee, though I think it only works once
Mr Backlot doesn't do anything when you haven't obtained the national dex. After you do, go talk to him and he'll go away for a while but then he'll come back. He will tell you that there is a Pokemon in his garden. That Pokemon is usually non-sinnoh native such as porygon. That Pokemon will be there for that day and tomorrow.
After you obtain the National Pokedex, talk to the owner of the mansion that likes to brag about rare Pokemon in his garden. It will be a different Pokemon every day.
to get espeon an umbreon in diamond first you need eevee, to get on you can go to the house next to the Pokemon center in Hearthome city and talk to the girl after defeating the elite four and answer yea to her question and she will give you an eevee or you can trade for them. espeon.... you need to level up your eevee during the day umbreon.... you need to level up your eevee during the night hope it helps :D
