Answer 8

You make Happiny evolve by letting it hold an Oval Stone. Then, you just raise it up one level during daytime. You can find an Oval Stone on some wild Happiny or Chansey. There is also one in the Lost Tower close to the entrance to Solaceon Town.

Edit: Happiny does NOT evolve by happiness. That would be Chansey. If it even evolved by happiness, it would of evolved already.
