Fullmoon Island is an island located in the northwest area of Sinnoh where you can catch Cresselia. You first go there to get the Lunar Wing from Cresselia, which she drops when she flees, for the sailor's son, in order to wake him from his nightmare. Then, you can track Cresselia with your Poketch.
