let happiny hold the oval stone and train it one level and it will evolve
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.
JUST Happiny can evolve from the oval stone.under ground digging
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!).
it doesnt evolve at a level. you evolve it with happiness.. like happiny, budew, togepi
it doesnt evolve
With high friendship. Give it a soothe bell or something.
It evolves Happiny. When Happiny levels up during the daytime while holding the Oval Stone, it will evolve into Chansey.
blastoise doesnt evolve.
Only Happiny, for all I'm sure of.
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.
