Fullmoon Island Platinum · Area
Fullmoon Island is a small wooded island reached by boat from Canalave City in the post-game. After you enter the Hall of Fame and get the National Pokédex, the son of a sailor in Canalave City is trapped in an endless nightmare. The sailor takes you to the island, where Cresselia appears and flies off to roam Sinnoh. It leaves a Lunar Wing behind, which you take back to Canalave to wake the boy.

Tips
- The event starts in the sailor Eldritch's house in Canalave City once you have entered the Hall of Fame and have the National Pokédex.
- Cresselia (Lv50) leaves as soon as you meet it and starts roaming Sinnoh; track it with the Marking Map app on your Pokétch.
- Pick up the Lunar Wing where Cresselia stood and use it on the sleeping boy in Canalave City.
- A Pokémon with Mean Look or another trapping move makes the roaming Cresselia much easier to catch.
- If you knock Cresselia out, it returns to Fullmoon Island after your next Hall of Fame entry.
