you cant. You have to live with Jolteon because its very unlikely Bebe would have given you a girl Pokemon so you could get your Jolteon to lay one, unless you do have a girl Jolteon-give it to the daycare lady in Solaceon town and finally it will lay an egg!
give it a sun stone
You can breed jolteon with a ditto its gender doesn't mater i got 6 evee eggs.
Either Jolteon, Vaporeon depending if you want an attacker (Vaporeon) ir a substitute passer (Jolteon).
problably jolteon
No, once you evolve a Pokemon you can't turn it back.
pikachu into raichu and evee into jolteon
i have Pokemon soul-silver and i evolved my evee using a thunderstone
to get another evee in platinum trade a ditto from another game and then keep your first evee ,jolteon,flareon,or vaporion with the ditto in the day care centre .come back after some time and the husband of the day care woman will give you an egg which will hatch into another evee.
Pokemon 135 is a Jolteon you must get and evee and put a thunderstone on it!
the Pokemon are pikachu and evee to jolteon and that is all
vaporeon, jolteon, flareon, espeon, umbreon, leafeon and glaceon 7
I found one on route 120, and used to thunderstone to get a jolteon from it.
