Hey everybody my name is Daniel. I'm currently playing pokemon platinum and I've beaten every single gym, and elite four. I've caught Giratina, Uxie, Mesprit, and the last one...(forgot at the moment) My question is how do you get Cressialia? Because I've got the lunar wing from Pokesav and I talk to the people and I still can't go to the island. I've gotten full Sinnoh Pokedex but, not National yet. Also where can you find Palkia and Dialga?
