you cant
No, you cannot.
you must have already found this out but eevee does not evovle into anything using a moonstone. -RR14
Moonstone
You can't make eevee evolve into espeon by leveling it up. You have to give it a certain stone. I think it might be a moonstone, but maybe that makes eevee evolve into umbreon.
In ANY GAME!! If you use a moonstone, i think
To get an Umbreon, you have to trade your Eevee to Pokemon Ruby, Sapphire, or Emerald, because there needs to be time if you're going to evolve Eevee into Umbreon. Keep Eevee with you until its happiness is at its highest, then evolve it with a moonstone WHEN IT IS NIGHT ACCORDING TO THE GAME CLOCK.

No, Eevee does not have to evolve to breed.
Eevee can not evolve into porygon.
eevee can only evolve once but if you get another eevee (of different gender )and breed with it you can get another eevee and evolve it into something else.
nothing,i think
