You tried to catch shaymin's sky form but she won't give you the flower though you have shaymin Did walmart rip-off my game?

Answer 1

You can only get the sky forme of Shaymin in Platinum. You have to catch Shaymin in its land forme from Seabreak Path in Pokemon D/P, then transfer it from D/P to Platinum. You get the flower from a girl in Floaroma Town in Platinum. If your game isn't responding correctly then contact the makers or the shop. I highly recommend going onto the Platinum website and reading about Shaymin. It tells you about Shaymin's Sky Forme and how to get etc.
