Actually, I have a cheat for my Pearl that gives me the Manaphy egg (since you can't get another after transferring it in Ranger, and I'm waiting for Plat. to be released in America so I can send over my Manaphy egg from there), so perhaps I could trade that to you for the shiny Wobuffet?
Um... Lemme think about that... ><' I might actually attempt to duplicate it, with a test, first.
Any Manaphy can have this kickarse set. Here it is as follows:
Item: Damp Rock
I don't know if you know why it's good, but...
Have Manaphy use Rain Dance. With Damp Rock, the effects of Rain Dance will last longer. Use Tail Glow as much as possible. But if Manaphy gets on low health, use Rest. Manaphy will not only recover all its HP, its ability allows it to recover from any status problem while it is raining. In the end, use Surf to deal massive damage (it's the best Water move a legit Manaphy can learn).
I saw. But obviously, Banaphy is the way to go XD And the thing's completely legit. No cheating required to get it. Just give it the almost unbeatable moveset and the correct item, and yeah... Plus, mine came from Ranger
