fire stone evee
In Pokemon Diamond, Pearl, and Platinum, if you want to evolve your Evee to a Leafeon you go to the Eterna Forest You will have to level up your Evee there and once it levels up by one level, it evolves to a Leafeon. If you want a Glaceon, you level up eevee on route 217. To get a Flareon, you give Evee a Fire stone. For Vaporeon, you give it a Water stone. And for a Jolteon, you need a Thunder stone.
mostly: evee------flareon vulpix-----ninetails growlith---arcanine
Evee - Flareon Vulpix - Ninetales Growlithe - Arcanine
there a snowy stone near snow point city level up eevee near that rock and eevee will evolve into glaceon.
it does not need a certain level just give it friendship in the daytime
No because there is no clock in leafgreen you must trade evee to a game with an internal clock to make it evolve to evee those games are ruby, sapphire and emerald also heartgold, soulsilver, diamond, pearl and platinum.
EVEE evolves at level 15
You Have To Use A Moon Shard And It Has To Have Max Hapiness
In Pokemon HeartGold and SoulSilver, an Eevee cannot evolve into a Glaceon. You can trade with other trainers from Diamond, Pearl and Platinum to get one.
