So, how exactly do I evolve my Eevee?
I want Espeon.
you can't.
while you can obviously HAVE them in fire, you can't -evolve- them in fire.
a moon rock? have you tried it? it doesn't work
what you'll need to remember, is that eevee evolves into umbreon/espeon based on the time of the day. there are no clocks in fire/leaf, which is why you can't get either one in fire/leaf
HOWEVER, when you start ruby/sapphire/emerald, you're asked to set the clock. so! if you trade over your eevee to one of those games, and make it happy on that cartridge, it will evolve into the pokemon of your choice (espeon is day, umbreon is night) and then you can trade it back to your fire cartridge so that it can level properly.
