oval stone is for certain bird Pokemon
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.
let happiny hold the oval stone and train it one level and it will evolve
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!).
JUST Happiny can evolve from the oval stone.under ground digging
It evolves Happiny. When Happiny levels up during the daytime while holding the Oval Stone, it will evolve into Chansey.
it doesnt evolve
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 doesnt evolve at a level. you evolve it with happiness.. like happiny, budew, togepi
Only Happiny, for all I'm sure of.
blastoise doesnt evolve.
You evolve Happiny by giving it an oval stone and you level it up once at daytime and it will evolveinto a Chansey.
give it 2 a happiny to hold and it will evolve to a chancey when its happiness maximises
