The best and easiest way to evolve Happiny is to equip it with the oval stone and level it up in the morning or evening. This will allow Happiny to evolve into Chansey.
the easiest way; in hearthome city, talk to a fat hiker and he will give you an egg and when that hatches then it will be a happiny.
search what you need then print it out " Easy"!

You can get a Happiny egg by going to Hearthome City and going all the way to the bottom then all the way to the riqht and talk to the fat guy and he gives you the egg have an open spot for it though.
take that fan out and then clean it. ( then put it back in)
It is not possible to trade a Happiny to leaf green, not only because a Happiny does not exist in the Leaf Green pokedex but you can only transfer Pokemon from FireRed/LeafGreen/Emerald/Ruby/Sapphire to Diamond/Pearl/Platinum, and not the other way around.
It depends on the operating system but the best and easyest way to do it is to reinstall the OS (linux, xp, vista, 7, mac, snow lapord, ect...)
Without cheats, you can only obtain Arceus through a Pokemon Event.
physical therapists help a lot
buy a Pokemon carictor or use ir money in Pokemon revolution
the easiest way would be to go to one of their signings, but that might mean that you have to stand there for a good few hours
Find it north of Solaceon town or evolve a Happiny
