Really need help here. Trying to evolve my Happiny! I have looked everywhere and one place said something about inviting Carlos from Extralink? But I'm not exactly sure how to do that. I have no friends with White or White 2 so I can't connect to anyone. Or is there anywhere I can get a Chansey?
Oval Stones can be found in the dust clouds that appear in caves.
You can also trade one from B/W if you want.
Black: Caves, Black City
White: Caves, occasionally held by wild Happiny.
