He is the sleeping pokemon blocking the entrance to cycling road and past vermillion city
move the dot on ur radio to the very top. this is the pokeflute channel. use it in front of the snorlax to wake it up. it will attack and you should probably catch it. its the only snorlax in the game.
get the pokeflute.
stuff you snorlax i have been playing for 7 months and cant get past him
Use the Poke Flute
you have to have a Pokemon flute
Use the Poké Flute to wake it up, and then you have to battle it. The sleeping Pokemon is Snorlax, and there are only two in the game, so it is best if you capture it. The Poke Flute can be obtained from Mr. Fuji, a kind old man who lives in Lavender Town. To meet Mr Fuji and obtain the Poke Flute from him, you must climb to the top of Pokemon Tower (in Lavender Town) and thwart Team Rocket. When you are back in his house, he thanks you and hands over the flute.
past special event
In Pokemon HeartGold and SoulSilver, the safari zone is in Johto, past Cianwood City, past Routes 46 and 47.
go to lavender town, go into the radio station and speak to the man by the water cooler, he will give you a kanto radio card, go to snorlax, open the pokegear radio and tap the top of the circle on the bottom (it should now say 'pokeflute') exit the pokegear and press A facing snorlax. now capture or defeat it.
