if all u need is to see happiny, this hiker gives u an egg to the left of hearthome city.he is inside the city but near the exit to the left
i dont know either iv been looking forever too EDIT: You can find Happiny in The Trophy Garden, but it's only a 5% chance a Happiny will appear. A trainer on Route 210 has it
You'll have to get it or see it at least. You can get it by:Transferring it to Pokemon BlackTrade for it.You can probably find a trainer in-game to battle you with Happiny.
96 would be Happiny. A trainer on the south side of Route 210 has 1 - the trainer's name is Pokémon Breeder Kahlil.
YOU GO TO A SHOP in Bobby boo town
pokemon breeder in route 210 he has pichu, happiny,pikachu
To see it there is a Trainer with one in a house north of Solaceon town. However to catch one you can find it in the Trophy gardens in the mansion on Route 212.
The route above Solaceon Town, there is a Moo-Moo Milk cabin there. A pokefan trainer(I think) has a happiny. She is below the cabin. In other news, quack quack.
You must have heard a rumor then. Because you can't find Happiny in Mt. Coronet.
Happiny will evolve only when it has max friendship with its trainer it can be level 100 when it evolves if you don't treat it good the earliest level you can get Chansey is level 2!
Happiny is in Trophy Garden as one of the Daily Pokemon.
You find it in the Pokemon mansion. I'm not to sure but that is the place to find Happiny in diamond and pearl.
i don't know but you can get the egg from a hiker in hearthome no that's pearl/diamond you have to get a national dex first then you can see happiny in trophy garden Save route 109 and 110
