if u want to move the snorlax, u have to fix the problem t the power plant, then go to the radio station in lavender town and talk to a man and upgrade your radio (or pokegear). Then walk up to the snorlax and open your pokegear, move the tuner around the top and find the poke flute, then talk to the snorlax. you should probably save before battling the snorlax.
