Imran: Yes Snorlax can learn giga impact. When I caught the Snorlax Lvl50 that was sleeping in front of Digletts Cave it knew Giga Impact in Pokemon Heartgold and Soul Silver. I do not know about other pokemon games in which you can catch Snorlax that they would know Giga Impact or not. But of course you can teach Snorlax Giga Impact with a TM. So, yes Snorlax can learn Giga Impact.
If you catch a Munchlax or Snorlax, they will have one. Otherwise, you can't get one.
Give it a full incense and breed it to get a Munchlax egg.
He is the sleeping pokemon blocking the entrance to cycling road and past vermillion city
Viridian City is in the Kanto region. You'll be able to get there by going through Diglett's cave after waking the sleeping Snorlax.
Ok, first you go to the place where the sleeping Snorlax was. The snorlax will no longer be there. You go in the hole and there it is.
Play the channel Pokeflute on your gear near him then talk to him. You ge the flute by talking to the old man in the radio tower.
Snorlax is a Pokemon. A Pokemon that spends most of its time sleeping, otherwise its eating and yes this Pokemon is quite big.
The PokeFlute is used to awaken Snorlax.
Snorlax is found at the intersection of routes 11 and 12.
