I know how but I won't tell you how to get phione

in order to do it you get close together and start the pokemon pearl of dimond go all the way down untill it says something about pokemon ranger and it will be trasported wait untill the end and go to sunnyshore pokemartand there will be a guy that will give you the egg{make sure you have an empty space in your party}and here is manaphy. if you want to know about phoine just post another question I know it works because Ive tried both the manaphy and phione. phoine is worthless exept for the natinal dex but don't trade it because people will make ripoff trades for phione.
