You trade the red scale to Mr.Pokemon for the EXP Share. You get the red scale from the red Gyrados in the Lake of Rage. Hope it helped. =D
When you defeat the red GYARADOS in the lake of rage you will find a RED SCALE in your pack.Go to Mr.Pokemon's house and give him the red scale and in return he will give you EXP. SHARE.
You can't trade Pokemon from Pokemon Gold to Pokemon Red, you can only trade Pokemon from Red to Gold and not the opposite.
you get the gyrados scale after defeating or capturing the red gyrados,then if you show it to mr pokemon,he'll trade it for an exp share
If it's like heart gold for this, then catch the red guarados, and u should get a red scale, go to mr.pokemons, house, and he will want to trade your red scale for his exp.share. Say yes, and u have an exp.share
