When you reach the Kanto Region (particullary Cerulean City you'll understand). A Team Rocket Grunt stole a machine part from the Power Plant but he dropped it in the Cerulean Gym Pool. After you battle him you can battle Misty in her gym. To find the Machine Part you have to use the Itemfinder in the gym. After you get it you return it to the Manager and he gives you Zap Cannon as a return. Then you have to go to the Radio Station and talk to the gentleman in the hat in the groun floor. He upgrades your EXPN Card to play Kanto Tunes. Finally go to Vermillion City and go in front of the Snorlax which is blocking the Digglet's Cave, go to your Poke-Gear and play the Poke-Flute tune, the Snorlax will wake up and attack. Then you can continue your journey to Pallet Town, Viridian, Pewter, Cinnabar Island and Seafom Islands.
