You can only get it on Heart Gold by getting a specific fossil.
manaphy; rotom
you can get it on Pokemon ranger then transfer it and on Pokemon planinum but i don't know how
the only legendary that you can breed is manaphy. and that will result in a phione.
No, you cannot breed Legendaries with the exception of Manaphy.
You can't, as far as I know. You have to trade it from your Pearl, Diamond, or Platinum game, after getting it from your Pokemon Ranger game. Or get it from a friend.There isn't a Manaphy encounterment in Soul Silver (unless you cheat), but there is a Manaphy egg event for Pokemon Ranger Guardian Signs and you can trade the egg to soul silver from Pokemon Ranger. You can then hatch the egg and it will be a Manaphy and the Manaphy is special because you can breed it to get a Phione. Also there might be a Manaphy event for soul silver coming up sometime later this year (2010). By the way you need to have a Wifi connection set up and you need to connect to wifi to get the Manaphy egg and the Manaphy from the event that may happen.only if it's traded from a different Pokemon game.
No, you can only get it by transferring the manaphy egg over to Pokemon Diamond or Pearl from Pokemon Ranger.
You can not get manaphy in heartgold/soulsilver. You will have to trade from diamond, pearl, or platinum.
You can only send Deoxys, Shaymin, Manaphy and Heatran, that are found in quests given by Wi-Fi.
It was ToyrUs Event. It is avilable if you buy a action Replay for the ds. Just go to there website and there will be a code for Manaphy.
Legendary Pokemon do not breed, so they cannot lay eggs. However, only one legendary can breed, which is Manaphy. If you breed it with a Ditto, you will get the uncommon Pokemon which is Phione.
sorry you have to trade it to Pokemon soul silver
I myself am not aware of this fact of finding Manaphy in Pokemon Silver, but my answer would be this cave you are looking for does not exist because Manaphy does not appear until Generation IV. If you are using cheats this answer is irrelivant.
