First,go to lavender radio tower and some guy will tell you about how the power plant is down or whatever. Then you go to the power plant and find out that they're missing a part to the generator or something and there is a shady person in the cerulean gym.Go there and beat him and he'll run to the bridge to the north.Talk to him and he'll tell you that he left the part in the life rings.Get the part and go to the power plant to turn the power back on.Then go back to the radio tower and get the little channel thing.Finally,tune into the channel then talk to snorlax and you'll battle him.
