I have found a glitch in pokémon that works really well! In fact almost too well. Go to Cinnabar Island and trade with one of the trainers in the place beside the Pokémon Center. After the trade surf along the shore line right beside the Gym. Now keep swimming along there until you see a pokémon named Missingno. (your game should be black for about 4 seconds before the battle.) Missingno. will be at level 80 with a high attack and low defence, speed, and special. Capture it (if you like) or finish the battle. He will not appear on your Pokedex. Now go to your item list and if the 6th item from the top is (lets say) a Rare Candy you will have appox. 130 Rare Candies!!!!!!! This item can be refilled by swimming again along the shore line beside!!! Note that it will not work with all items (eg. HM1.) Also you will see other Pokémon from the last place you were at. An example would be the Safari Zone!!! You can ditch the Safari balls and use your pokeballs instead!! (also once you leave the Cinnabar island shore line you will not see Missingno. unless the last place you were at was a town or the Elite Four. And once all the trainers to trade with are gone ((in the whole game))you cannot see Missingno. again!)
