Manaphy: You get Manphy buy getting two nintendo DSs pokemon d/p and pokemon ranger, you get Manaphy on pokemon ranger by doing this speacil mission but I forgot the code, any then when you completed the Manaphy egg mission go back to ranger net and say check egg then go to transffer or something like that and there you have the Manaphy egg on pokemon pearl. It hacthes after 2,000 somthing steps so I hope that helps and I'm sorry that I didn't have the code, I could have told you if I remembered it but I didn't.
Phoine: You get Phoine by getting a Manaphy and a Ditto put them in the daycare center and wate till it they lay an egg, but when you get it it won't hatch till 10,240 steps so it will take a preaty long time for it to hatch, and that's how you get Phoine.
I really hope that helps.
