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).

you have to have full friendship with it
Only Happiny can evolve with this item. When Happiny holds the oval stone during the day, it evolves into Chansey when leveled up at any level.
no..... but if you level up happiny while its holding an oval stone between 4 and 8 pm it will evolve into a chansey, which can breed :D
Give it to your Happiny at day time and level it up to evolve it into a Chansey.
I think you evolve Happiny into Chansey with the oval stone? They have to hold it and level up I think?
