Getting evee, jolteon, flareon, & vaporeon
Get the eevee from the roof of the mansion in celdon (go in the back) then make it evolve (i used one of those stone things but you can wait till it evolves by itself) and bring it to the day care on 4 island with a ditto (around the same level). After a while the guy outside wil move up a little and when you talk to him he'll tell you they found an egg. Hatch it (it'll be an eevee) then make it evolve and do the same thing again till you have all of them.
You can do the same thing to get a pichu. Leave a pikachu or a raichu with either a ditto or another pikachu or raichu (of the different gender) and the egg will be a pichu.
