You Need To go to the Lavender town radio tower get the radio card and then you go to pokegear, then go to the radio put the station selector all the way to the right it will be the pokeflute station do that next to the snorlax.
go to your radio and move the dot around until it says poke flute and the snorlax will attack you, I suggest you capture it.
Snorlax is south of vermillion city in crystal, you will need to finish a few things to wake him up tho, i suggest googling it because im not about to write it out :p
i think snorlax can
By obtaining pokeflute.
Black Apricorn: Heavy Ball -- Big enough to catch heavy Pokemon like Snorlax
you cant get a pokeflute on crystal, you wake up snorlax by getting the radio station pokemusic i think that is what it is called, on your radio, put that on and stand next to snorlax and he will wake up and boom lvl 40 or 50 snorlax cant remember exactly. lol
If you mean for the snorlax, if you have the card, walk up to the snorlax, play the pokeflute channel, and it should work
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.
pokeflute
use the Pokemon flute
Snorlax
Turn on the radio in the pokegear and tune into the pokeflute channel.
