The oval stone can evolve happiny into chansey, only if; happiny is holding it, and the time you are in while levelling happiny up is day time.
It will evolve a happiny to a chansey (but if you do that on Pokemon diamond or pearl i don't think you can get another happiny so beware!).
Only Happiny, for all I'm sure of.
You evolve Happiny by giving it an oval stone and you level it up once at daytime and it will evolveinto a Chansey.
Happiny is the only Pokemon that can evolve from a Oval Stone in Pokemon Diamond, Pearl, and Platinum. You will need to max its Happiness during the morning or day, let it hold an Oval Stone, and then level it up once. It will, then, evolve into a Chansey.
