How do I get exp.share and unlimited rare candy?

To get the EXP. Share, go to Mr. Pokemon with the Red Scale you obtained from the Red Gyrados in Mahogany Town's Lake of Rage. He'll exchange the exp. share for the red scale.

I haven't heard of unlimited Rare Candy but if you want, duplicate it many times, until you get what you want and this should help you.

Beat the red Garardos (take it off him if you capture him) get the red scale and take it to Mr Pokemon and get the exp share. You must be weak because the Elite Four are a piece of cake!

The only way to get infinite rare candy is with a gameshark. If you have one then type in the code 0120B8D5. In your items pocket, it will either show 99 rare candies or 1 rare candy. If it says 99, keep trying until it says 1. If it says 1, use that one and it should say zero. Good Luck.

If you're playing Crystal, you can get a Rare Candy every three days by playing the Buena's Password radio show game. But Rare Candies aren't actually that great unless you're trying to make a Pokemon learn a move or evolve, since their stats don't go up as much as if you actually train them.

To get exp.share baet or catch the shiny gyrados then you get the red scale walk or bike to mr pokemon's house.if you fly you will have to go to cherrygrove city and walk or bike to his house swap the red scale and you will get the exp.share.
