In Pokemon Diamond and Pearl what Pokemon evolves with the oval stone?

If you give the Oval Stone to a Happiny, it will max- out it's happiness. Then you just need to level it up once and it will evolve into Chansey.

NOTE: The Oval Stone only works on Happiny and no other Pokemon. So, it will not max- out another Pokemon's happiness. Sorry, but that's the way it is . . .

The Oval Stone evolves Happiny into Chansey. Give one to a Happiny, max out it's friendship, and level it up during the day. (I'm pretty sure the hours are 4:00 AM to 8:00 PM)

Note that the daycare, even if it levels up, will NOT evolve it.

Happiny evolves into Chansey, which if you can't evolve it via friendship, Chansey is available at around Lv.18 at Route 209, south of Soceleon Town. They're pretty rare, though.

the oval stone.

sadly it has one use, and that use is when happiny (chanseys pre-evolotion) holds an oval stone then being happy and being lvled up evolves into a chansey.

so you have 2? well what i would do is if you have GTS is put up your happiny for trade holding an oval stone and ask fora pokemon you need, you might be lucky enough to actually get it!

i hope i helped.

The only use for the item is to evolve happini into chansey.More can be found uderground.Though rare they are obtainable there.Hoppe i helped

Give it to a Happiny to hold and level it up during the day, maxing out its friendship. It will evolve into Chansey.
