You must train happiny during the day while holding an Oval Stone.
Chansey
you have to have full friendship with it
Actually, Happiny doesn't have to level up in order to evolve into a Chansey. You have to make it hold an Oval Stone first. Then Give Chansey a shiny stone to evolve it into a blissy. ------------------------------ Chansey evolves when you befriend it (not by a stone).
happiny into Chansey
a happiny evolves with happiness, not by level. when the happiness is really high, level it once, and it will evolve into chansey.
You can evolve Happiny into a Chansey if Happiny is holding the oval stone and leveled up during the day.
happiny into chansey
Chansey -Usyflad10 rules!!!!!!
You have to trade for Happiny holding an oval stone or go catch Chansey on route 209 and if you do one of those Happiny can evolve into Chansey who can evolve into Blissey or you can catch Chansey like I did and evolve it into Blissey.
Happiny evolves into Chansey only if Happiny is holding an oval stone. Also, you must have a HIGH friendship with it. (Same for Blissey, but no oval stone)
Happiny, into Chansey.
In order to evolve Happiny, you need to give it an Oval Stone and then level it up during the day and that will cause it to evolve into Chansey.
