get an eevee and evolve it into a thunderstone
To make Eevee evolve into an Umbreon, you have to level it up with high happiness at night.
Can only evolve from Eevee if it gains a level while on Route 217, so you must trade an Eevee over to Diamond, Pearl, or Platinum and evolve it there, since there is no Route 217 in HeartGold and SoulSilver.
you use a fire stone on eevee to evolve it into flareon thunder stone = jolton water stone = vaporeon full happenes in day you get espeon night time you get umbreonYou cannot evolve an Eevee into a Glaceon in Pokémon HeartGold, you would have to trade it to either Pokémon Diamond, Pokémon Pearl or Pokémon Platinum and evolve it into a Glaceon there and then trade it back to HeartGold.
In Pokémon HeartGold, you can only evolve Eevee 5 ways which would be: Using a Fire Stone on an Eevee into to evolve it into a Flareon, use a Thunderstone on Eevee in order to evolve it into a Jolteon, use a Water Stone on Eevee in order to evolve it into a Vaporeon, evolve it into Umbreon via level-up at night (which is between 8PM and 4AM) when it's happy enough and evolve it into Espeon via level-up during the day time. You can also evolve Eevee into Glaceon and Leafeon however evolving Eevee into Glaceon or Leafeon is not possible in "HeartGold" or "SoulSilver," Eevee can only evolve into Glaceon via level-up when it's near the Ice Rock which can only be found in the Sinnoh region near Snowpoint City and Eevee can only evolve into Leafeon when it's near the Moss Rock which can only be found in the Sinnoh region which is in the Eterna Forest.
