Keep it in your party, battle with it but don't let it faint, if you have entrance to that club in the resort area take it to be groomed, feed it items (but not herbs/natural medicine), and feed it poffins.
The easiest way to increase Eevee's happiness to maximum happiness is to do as follows:
1. Let it battle a lot.
2. When it's battling, do not let it faint at all.
3. Use vitamins on it.
4. Feed it berries.
5. Give it massages. In Diamond, Pearl and Platinum there are 2 places that give massages. 1 in Veilstone City and 1 in the Resort Area. In HeartGold and SoulSilver Daisy in Pallet Town will give massages.
same way youd get it on another version eevee happiness level up after 10pm
You get it by making it max friendship can do it faster if you give it a massage at one veilstone city's houses. If you have a poke app that tell you the friendship you can see it .Give it a poffin and a massage then it will get to a umbreon no time. P.S.: Do it at night or it will be espeon.
The duration of The Easiest Way is 1.22 hours.
If you want Eevee to evolve into Espeon then train it during the day, other way 'round for umbreon (On LGFR you need the National Dex)

Sorry to say but, eevee doesnt evovle into umbreon by level. The only way to make it evolve at night with high happiness
If you have made your eevee evolve and still need to get data on a different evolution the easiest way is to breed the eevee evolution (Vaporeon for example) the resulting egg should hatch an eevee that you can evolve into something different.
if you want to evolve eevee into umbreon i suggest give the item "soothe bell" to eevee then level him/her up untill he/she evolves its just like golbat he needs max happiness to evolve all you need for golbat is a soothe bell and training same for eevee!!!! how do I know: i have the game and it worked perfectly.
Eevee will evolve into Espeon at max happiness. However since FireRed/Leaf Green have no internal time you will need to trade to Emerald. (Since by now Ruby and Sapphire's internal clocks are no longer working and day/night doesn't happen anymore) and I've not tested Emerald's. In order to get an espeon you have to have its friendship in the evening. To evolve eevee to espeon certain conditions must be met. It must have it's happiness all the way up. It mus be between 12pm and 12am. In Pokemon XD, one could use a sun shard to evolve eevee into espeon. _________________________ When you give it happiness (on heartgold) go check in Goldenrod City the happiness. If it says-"I think your Pokemon really trust you" level it up and it will evolve.

Eevee is unobtainable in Ruby, Sapphire and Emerald. You must trade it from someone who has Firered or Leafgreen. But if you happen to have FR or LG or you are going to get it, then you obtain Eevee in Celadon city. You must head up to the top of the Mansion there. (I think you have to get in from the back) then head all the way up to the top floor. There will be a man facing a board. Talk to him and he will tell you to take that Pokeball on the table which contains Eevee, and this Pokemon evolves into 5 different kinds of Pokemon: - Eevee into Vaporeon= Water stone - Eevee into Jolteon= Thunder stone - Eevee into Flareon= Fire stone - Eevee into Espeon= Happiness during the day - Eevee into Umbreon= Happiness at night... From the Pokeknowledge master
Max out Munchlax's happiness and he will evolve. The easiest way to bring up happines is by having the Pokemon in your party and make sure it doesn't faint. Also don't use the organic medicine as that brings down happines.
The easiest way is to buy Action Replay Max for the Gamecube, and activating the "Have All Trophies" hack.
There's 2 ways you can get an Eevee in Soul Silver.The easiest way is to get one from Bill.You first meet him in the Eretucut City's Pokecenter.Then you go back to Goldenrod City and talk to him in his house.He'll give you an Eevee.The other way is to go to the Game Corner in Celadon City and buy an Eevee for 6,666 coins.
Know yourself, know what you want, know your limitations
Here is how you evolve it into different Pokemon:Jolteon: use a Thunderstone on it.Flareon: use a Fire Stone on it.Vaporeon: use a Water Stone on it.Leafeon: level up your Eevee near Moss Rock (found in Eterna Forest.)Glaceon: level up near Ice Rock (found on Route 217, on the way to Snowpoint City.)Espeon: level up with max Happiness in the daytime.Umbreon: level up with max Happiness in the nighttime.
