Happiny evolves when it's leved up while holding an oval stone
It evolves to chansey by holding a oval stone and making it happy. First, it hatches from it's egg and obviously is a Happiny and when it's leveled up holding an Oval Stone, it evolves into Chansey. Chansey evolves into Blissey via happiness. So the evolution is Happiny, Chansey, and Blissey.
In Pokémon Diamond, you use the Oval Stone in order to evolve a Pokémon called Happiny however you need to give the Oval Stone to Happiny itself instead of using it on Happiny. Once an Oval Stone is attached to Happiny then you just need to level it up once while it's the day time in Pokémon Diamond and it will evolve into Chansey.
Because it's not oval enough. Get a dictionary.
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.
