migrate or give to pokemon diamand or pearl touch that. When it says that it's finding the
game thingy you get your other DS and put on diamond/pearl and go to main menu. Wait a
moment then it will say "message from Pokemon Ranger" get to that and it will take you
somewhere. Just follow everything that will get u the manaphy egg then it says migrated to
pokemon pearl/diamond. But I don't know where to get the egg if anyone knows this tell me
I don't know where my egg is!!!

you go to a pokemart and talk to a man in green and he will give you the egg
