Pokémon Diamond and Pearl/Manaphy Egg Quest

The Manaphy Egg
is a "Legendary" Pokémon, similar to Mew and Celebi in many ways, most notably that to get it requires an outside source (outside of the Generation IV Pokémon games), and its base stats are all the same at 100, the same as Mew.

Supplies

 * Two (2) Nintendo DS Systems (for transferring the egg)
 * One (1) Pokémon Diamond or Pearl game
 * One (1) Pokémon Ranger game
 * A couple of hours

The Manaphy Code
The Manaphy Code is not the actual code to obtain Manaphy, it is to obtain the extra mission in Pokémon Ranger to get the egg. To unlock the ability to even get to put in the code, the player must complete all normally required missions of Pokémon Ranger and complete the 3 other extra missions. After that, when the player goes into the menu that allowed for the extra missions, they also have the choice, after pressing "R", "X", and Left simultaneously, to enter a code, which for the American version of Ranger is P8M2-9D6F-43H7. This is the code that is what most people are looking for.

After completing the Manaphy Egg extra mission, the egg is now ready to be transferred.

Transferring the Egg
To transfer the Manaphy egg, the player should turn on the Nintendo DS with the Ranger game already inserted, go to the main screen, then the Ranger Net option, and choose to send over the egg and follow all directions that it gives the player to transfer. After the egg is transferred onto the Pokémon Diamond or Pearl game, the player should then go to any Pokémart and talk to the man in green to receive the egg. The egg will hatch with time, yielding a level 1 Manaphy.

Getting Phione
Phiones are the result of breeding a Manaphy with a Ditto. Putting both a Manaphy and a into the Day-Care and walking around for a short amount of time should yield an egg, which will hatch into Phione.

is currently the only Pokémon that can be obtained by breeding a legendary.
