Pokémon Pearl Version (Italian) - Catching Cresselia

After getting the National Dex, go to the Sailor’s house at Canalave City and he will tell you about a Pokémon that is tormenting a sleeping boy. The boat will take you to Fullmoon Island where Cresselia awaits. After you interact with Cresselia, it will leave a Lunar Wing behind and roam all over Sinnoh. Use the Marking Map on the Pokétch to track the movements of roaming Pokémon. Cresselia is on Level 50. Remember, roaming Pokémon flee on the first turn. If you still have the Master Ball, you can use it. Otherwise, have a Pokémon that knows Mean Look and use Dusk Balls at night. If Cresselia reaches Level 84, it will learn its signature move called Lunar Dance. When the Lunar Dance is used, the user faints and the next Pokémon sent out will be fully healed.
