In pokemon heartgold, how do you get wake up the sleeping snorlax on route 11?

The one blocking the diglet cave,right now i'm stuck with only 13 badges unless i get rid of that snorlax, so i can i wake it up?


You have to get power back to the Power Plant at Cerulean city and talk to the radio guy in Lavender town. He will give you a new radio card that has the pokeflute music on it. Play it near the snorlax and he'll wake up.


You need to get the expn card to listen to radio in Kanto, the pokeflute radio station should be at the top in the middle but not labeled you just have to click there
