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 have to level it up with a good level of happiness thunderstone works in a different game

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
