You need to make it really happy then use an oval stone on it, to evolve it into a chansey. Then, get it really happy again and it will evolve into a blissey.
I'll tell you now, it's a really boring process...

Happiny
you have to give it something and then level it up and it will evolve in Pokemon pearl
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 a Chansey when it levels up holding the Oval Stone during the day.happiny evolves with the oval stone.......... I thinj
With an oval stone, you can evolve Happiny into Chanssey.But, you need to make Happiny hold that stone and then level it up in order to evolve.
You can evolve Happiny into a Chansey if Happiny is holding the oval stone and leveled up during the day.
Only happiny.
Happiny, into Chansey.

Happiny, but she has to hold it.
I believe that it is happiny
let happiny hold the oval stone and train it one level and it will evolve
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.
