Was it the time from the Pokemon game? From 12:00PM~12:00AM? Check that. If still nothing happens make sure on User:Blue%20Harvy.
This is a great Website, but Eevee can go two 5 forms, in Heart Gold and/or Soul Silver. Eevee----> Jolteon by a ThunderStone Eevee----> Vaperon by WaterStone Eevee----> Flareon by Firestone Eevee----> Espeon by Friendship and then leveled during Day Eevee----> Umberon by Friendship at max and then leveled at night. http://serebii.net/pokedex-dp/133.shtml Is all the moves, where to get, and everything you could know about Pokemon.
Vaporeon: Water stone Jolteon: Thunder stone Flareon: Fire stone Espeon: Happiness & leveled @ day Umbreon: Happiness & leveled @ night Leafeon: Leveled up @ mossy rock (Enterna Forest) Glaceon: Leveled up @ frozen rock (Snowpoint City) You can get an Eevee either by migrating it from FireRed/LeafGreen or receive one from Bebe.
only way is for eevee's happyness must be maxed out and leveled up at night ~megapikachu~
To get Umbreon in Pokemon Crystal, you need to evolve an Eevee into an Umbreon. Eevee evolves into Umbreon when it levels up with high friendship during the night or when leveled up with a Moon Shard. To increase friendship, you can keep Eevee in your party, use it in battles, give it vitamins, and avoid letting it faint. Make sure to level up Eevee during the night to evolve it into Umbreon.
Eevee can evolve into seven different pokemon:Vaporeon (Evolves with a Water Stone)Jolteon (Evolves with Thunder Stone)Flareon (Evolves with Fire Stone)Espeon (Evolves when it is leveled up with high happiness during the day(10:00 AM to 5:59 PM))Umbreon (Evolves when it is leveled up with high happiness during the night(6:00 PM to 3:59 AM))Leafeon (Evolves when leveled up in the Eterna Forest, which has the moss rock)Glaceon (Evolves when leveled up near the ice rock on route 217)
Eevee, can evolve into several types of Pokemon Leafeon, Glaceon, Vaporeon [ with a water stone], Jolteon [ with a thunder stone ], Flareon [ with a fire stone ], Espeon [ happiness full and leveled up during the morning ] and Umbreon [ happiness full and leveled up during night ] there is a stone where you have to evolve eevee near to get leafeon in i think eterna forest and there to get glaceon, you need to find a stone near snowpoint city eevee, by itself, isn't very helpful in my opinion.
you have to raise eevee at night
Train your Eevee at night and with happiness. It will eventually evolve into Umbreon.
Ok first of Eevee does nto evolve into Umbreon because of it's level it evolves from happiness, when it has max happiness at night and it is leveled it will then evolve! So get into lots of battles at night and make sure that it doesn't faint and with a bit of luck you should have one soon~
You train an Eevee at night.
You have to get eevee to max happiness and level him up during night.
Nothing.
