you have to catch them in the forest of picachu
golbat,pichu,azurill,igglypuff, Those are the Pokemon for freindly evalution golbat pichu igglybuff and azurill
To evolve a pichu you must make its happiness level to full. then once youv done that use a thunderstone, located in the underground solaceon ruins in Sunnyshore city with the dowsing machine, to evolve a picachu into a richu. Hope this helpedXX
You can't catch pichu in Pokemon emerald,But you can get a male pikachu and a female pikachu or a ditto and breed them, When the egg hatches it will be a pichu
you have to level it up with a good level of happiness thunderstone works in a different game
Pichu evolves by happiness.
Leave a picachu with a ditto at the babysitter. Eventually they will find an egg. Walk around with the egg in your party and it will hatch into a pichu
go to trophy gardens south of haerthome and catch a male pichu and raise it
Pichu evolves by happiness.
Riolu evolve's normally and pichu evolves through happie'ness
pichu does not evolve at a level,it evolves with a high friendship.Pichu can evolve at any level if it has enough friendship.
Maxed out happiness
