In Platinum, you must talk to the sailor in Canalave City and he says his son is having bad dreams. You can have him take you to Full Moon Island, which Cresselia is inhabiting. When you get to the clearing where Cresselia is in, it will escape and start roaming Sinnoh. You can find out where it is using the Poketech. When it dissapears, it will drop the lunar wing. You cannot get the lunar sing in Soul Silver.
