After helping the power plant by giving them the missing machine part you can receive a EXPN card from the lavendar town radio tower from the director now tune into your radio and put the line near the end of the radio you will soon find a pokeflute channel this is how you wake up snorlax by putting the radio next to it while the pokeflute channel is playing.
to awaken snorlax
you can't. it's on the radio in kanto only
Get it from the old man in the Radio Tower at Lavender Town.
when you have your pokégear,go to the radio an use the touchscreen to go to the top of the circle
you use the radio and go to the top near snorlax it should work
use the pokeflute but if ur in heartgold or soulsilver, move the dot on ur radio to the top of the circle (pokeflute channel)
The pokeflute channel is a completely separate channel on the radio you can only tune into it in kanto put the frequency almost near the top to find it.
In Heartgold and Soulsilver, the pokeflute works through the radio in kanto AFTER you beat the Pokemon tower. You just turn on your radio and tune it to the top of the circle, and the pokeflute plays.
you need to put the raido channel up to the top of your radio. it will have the effect of waking Snorlax up.
I thought the same thing at first, but turns out, ITS ON ALL THE TIME! Move the cursor thing to the very top at the center, and a thing called "Pokeflute" will play! :D
there isn't pokeflute in Pokemon pearl or diamond
Pokeflute is on the Pokemon radio when you are in Johto or Kanto.
