Changing Shaymin's Form
If you have a Shaymin on Pokemon Heart Gold or Soul Silver, put it in the front of your party and walk in to the Flower Shop in Goldenrod City. The lady will take a look at it and give you the Gracidea Flower (normally just called the Gracidea). It will appear in your Key Items pocket in your bag. Click on it then press use, then click on Shaymin (this will only work at Daytime) . A bunch of flowers will appear over top of it's icon and vwallah! Shaymin is now Sky Form! If you want to change it back to Land Form wait until nighttime. I hope this helped!
