Okay, after defeating the elite four and the champion, go to Canalave City.At the sailor's house, who takes you to iron island, his boy would be sick.After talking to the boy, just go out and talk to the sailor.He will then take you to Full Moon Island(here you will encounter Cresselia and then get the Lunar Wing, to cure the boy)
Hope this helps :)
there is no fire island on platinum there is full moon island and crsent moon island (were you catch cresilia and darkria) and iron island that is it
Getting to the Moon in PokemonIt is not possible to get to the moon in the Pokemon gameboy games. You can get to MOON ISLAND in Pokemon platinum; that is where you meet Cresselia.Acually it's full moon island where you meet Cresselia.
Darkrai Can Be Found On New Moon Island. Darkrai Can Be Found At New Moon Island,Next To Full Moon Island.
You need action replay or the black card.
visit full moon island and look for it in the wild
there is iorn island, full moon island, and new moon island
nothing. that flute is for arceus
Half Moon Island does not exist in Pokemon Diamond, Pearl, or Platinum (or any Pokemon game). The only two islands named after moon phases are Full Moon Island and New Moon Island, and the closest place to either of these two islands is Iron Island.
New moon island is only avalible in Pokemon pearl, diamond and platinum
iron island, (where you meet riley and he gives you a riolu egg,) Full moon island,(where you first see cresselia,) and New moon island (where you catch darkrai)
You have to beat the Pokemon league first and get the national pokedex. Then go to canalave city and go in the sailor's house. Talk to the woman inside the house. Then go outside and talk to the man and he will bring you to full moon island.
On New Moon Island.
