I tried to find this info on many FAQ but I did not finf it...

In past pokémon games, there were some way to teach your pokémon forgotten or erased past moves.

Is there a way to do it in pokémon pear and diamond?

THX

In Canalave City(Where you get the 6th badge and where you the Darkrai event is and the library is) below the PokeMart there is a house with an Old Man who says he's forgets who he is that's the Move Deleter he'll deleite any move even the HM's.

Thx but I know about the move deleter. What I want to know is if this is possible for exemple to teach back water gun from your squirtle if you erased it?

oh i misread there is a man in Pastoria City that will teach your Pokemon moves they knew/could of known in the past in exchange for heart scal.

his hose is south of pokemon center

ya pastoria, one move per heart scale.

Yes, there is a way. I can look it up if you really need to. There is someone, somewhere, who you can give Heart Scales to. You can choose one Pokemon to remember one move for each Heart Scale you have.

EDIT: Beaten by ten minutes!

And how do you get those Hearth scales?

heard scales can be from catch luvdisc (they have item attach) or mine them underground in Sinnoh.

undergroud is the best becasue they are really common like reallllly common my son :)

Hey thank all. I might finally get back that defense curl for Blissey

Might I suggest just teaching Blissey Light Screen? It halves physical damage for 5 turns, and even stays if you switch out Pokemon.

I think it's much more efffective...

If you've taught it some great Special attacks, I'd also recommend Calm Mind instead. It brings up SP AT and SP DEF at the same time. I believe Blissey's SP AT is inherintly much better than her regular physical attacks, but you can check to make sure.
