How do you get Espeon and Umbreon?

Easy,do you have a Eevee if you do then this will be easy,if you don't I would get one, first off lets start off with Umbreon ,you need to give eevee lots of hair cuts,potions,hp ups,calceum ect...

(you can buy these at goldenrod)

Battle with Eevee alot,if it likes you during day and it evovles and it really likes you,it will turn into a umbreon,this is the same with Espeon but you need to make it eveolve during night,good luck and hope this has helped.

The only ways to obtain Espeon and Umbreon is to get their friendship/ love levels up as much as you can, if you peak out Eevee's level in the day you wil get an Espeon next time is gains a level, you get an Umbreon when you peak it's level out at night. hope I helped =]

I don't know if you can in crystal, but I do know how to get umbreon and espeon. In my guide book(that's how I know it works) it says you have to get eevee's friendship level as high as it can go. Then, if it evolves in the a.m., it will be an umbreon. If it evolves in the p.m., it will be an espeon. I don't remeber if you're supposed to use a moon stone or not. If that doesn't work, you may need to trade it to ruby or sapphire and evolve it. I know it will work there.

Get a evee and train it with love untill it's about to evolve if it evolves in day it will be espeon if it evolves at night it will be umbreon

They're friendship evolutions from Eevee-Umbreon if evolved in the AM hours, Espeon if evolved in PM hours.

Espeon- Make Eevee really happy at day. Next time it grows a level, it'll evolve.
Umbreon- Same as Espeon but at night.

Jamesiles06's response is mostly correct. However, it becomes an Umbreon at night and Espeon at day, not vice versa.

You have to have an evee only trane with the evee at night.Also In GoldenRod city,in the underground every night give it a hair-cut from one of the hair-cut bros.
It probably will cost 200-300$.that's how you get an umbreon

Umbreon: Make Eevee hit the maximum level of friendship with you during nighttime by letting it hold items, using items on it, using it in battle often, and not neglecting it.

Espeon: Make Eevee hit the maximum level of friendship with you during daytime by letting it hold items, using items on it, using it in battle often, and not neglecting it.
