yes
In Shaymin Village, If you talk to a certain Shaymin, it will ask you if you want a Gracidea. If you say yes, you will receive a Gracidea to use on the Shaymin on your team, wich will put Shaymin in its Sky Form. If you say no, wrong answer.
yes or get the oak's letter from the event which past
yes have shaymin in your party and talk to the blonde girl she'll give u a gracidea flower and use it on shaymin. the shaymin must be from the event.
Fortunately yes it does, only if you have the gracidea flower, unfortunately shaymin can only be turned into sky form in the day so you shaymin will automatically turn back in to land form at night. Understand, i hope i helped you alot
yes
Yes you can. First start a new game. (Make sure either Pearl or Diamond already contains Shaymin.) Then play your way through the game until you reach Florama town. Before you actually enter Florama Town, do a trade with either Pearl or Diamond and receive Shaymin. If Shaymin is in your party, talk to the girl at the front of the town. She will give you a Gracadia Flower. (Key Item.) Give the Gracadia Flower to Shaymin and it will trasform into Sky Form Shaymin. Note: Shaymin can only stay in Sky Form if: 1. It's daytime 2. It currently has no status problem (Maybe only frozen or burn.) and 3. Shaymin is in your party. (Meaning that Shaymin will go regular if it's in the P.C.)
Shaymin will transform into Sky Forme, when, yes, it's in Pokemon Platinum and when a Gracidea Flower is used during the Day. Shaymin revert back to Land Forme when it's Night or put in the PC. To get the Gracidea Flower, show the woman with the blonde hair in Floaroma Town Shaymin and she'll give you the flower.
