You can not catch a manaphy on Pokemon diamond. you must trade it somehow on a Pokemon rangers game.
A Manaphy is not available in the wild in the Pokemon world. You must trade a Manaphy Egg from Pokemon Ranger.
There was an event for manaphy egg.
You can't. You have to trade it in from another game.
You must breed a Manaphy to get a Phione.
There is no secret Pokemon in diamond and pearl but there are ways to get Pokemon you cant catch on diamond and pearl. For example manaphy. You must clear the manaphy mission on Pokemon ranger. Goodluck with the game!
after you get the national dex, go to the Pokemon mansion and look in the book there. you cannot catch manaphy though, you have to transfer it to palpark:}
you have to breed a manaphy with a ditto and hatch it or maybe get it in an online trade. manaphy was an event Pokemon so you cant catch it.
