150 Rare Candies:

After defeating Cipher Admin Venus in her broadcast center (in the Under) go to the room behind the camaera nearest the entrance and open the box to get 3 RARE CANDIES. Give any 3 of your pokemon 1 candy apiece to HOLD. Go to the nearest PC and save. Deposit those 3 pokemon and then move the pokemon to seperate boxes. Save the game. Once saved turn off the GameCube and turn it back on 2 seconds later. Load the saved game and enter PC, once in you'll see 3 boxes that contain items. Withdraw the previous 3 pokemon and take back their items. Each pokemon should now hold 50 RARE CANDIES apiece. Totaling 150 !
