3rd Gen Espeon & Umbreon/HELP PLZ!!!

I have the National Dex. I've made it to Four Island and the daycare. I hatched an Eevee egg. Now how the heck do I evolve it into an Espeon or an Umbreon??? :\

You have to trade it over to RS and evolve it there. Read the thread (link above) for more information.

You don't have to evolve it in RS. That thread was just made to prove if they would evolve in RS, in which they do. To get them to evolve, make them happy! Give them lots of vitamins such as Protein and stuff (but be careful if you're EV training), give it lots of attention by using it in lots of battles (again, be way if you're EV training). To actually account for which one it's going to evolve into, it depends on Personality Value, Gender Value and Nature Value. All of these have hidden numbers, and when added together, lie on a certain range. Espeon has one range, and Umbreon has another. So it's all about which Eevee you picked. Follow the steps above and you should eventually get one of them. ^_^

I have tried your method but it did not work. I have somthing that helps. It says that to get them you must trade eevee over to ruby and sapphire and evolve it here. It says so on the official Pokedex with all 386 pokemon. For the game the time is the key. At day make it happy and espeon is yours at night make it happy eumbreon. Just look at the time. That is all need more help just ask.
