how to evolve eevee into espeon or umberon =
ensure that your eevee has max happiness and level it up,
will evolve to espeon if leveled up in the day time,
or will evolve to umberon at night time.
but be careful if you are in the eterna forest the eevee may evolve into a leafeon due to the mossy rock (cant rember proper name) or if you are on route 217 to snowpoint city the eevee may evolve to a glaceon due to the icy stone (yet again proper name escapes me )
so please any evolution questions you have put them here
