Yes, you can. Every time you defeat the elite four, any pokemon that are special will reappear like the level 30 shiny gardose. Same thing goes with sudowoodo and snorlax.
To get past snorlax on heartgold you need to get the power back on then go to the Kanto raido tower and get the radio get up graded by the man with the hat then go to snorlax and play the pokeflute on the pokegear by moving the circle to the top.When you battle snorlax kill him or catch him.
Go to your Pokegear. After getting the Kanto radio card, you go to the topmost star in the circle of stars. That is the PokeFlute Channel. Leave the dot on it and exit your Pokegear. Then talk to snorlax. Snorlax is awake and ready to battle. Snorlax is lvl. 50 and tough.
Go to Lavander Town and get the Pokegear Radio updated by the Manager in the Radio Tower, Go back to Snorlax play the Flute Melody by going to the radio and moving the needle up and Snorlax will awaken and battle you when you press A on him/her.
You go to snorlax and use the poke flute and you battle him (poke flute is on the raido at very top of map
Breed Snorlax with another Snorlax.Since you can only get 1 Snorlax Heart Gold, you can trade for a Snorlax in the GTs or with a friend.The Pokemon egg you get should hatch into a Munchlax.
I don't know how to get it, but to play it you have to get you radio in your pokegear upgraded, go by snorlax, put the thing on the world map to the top and you will battle the snorlax level 50 and get through diglett cave to pewter city.
nearby diglett cave my friend just showed me
First you go to your pokegear, then go to radio, then drag the dot to the very top line, it will say Pokemon flute, then go to bag, go to medicine, you will find poke flute, go to snorlax, press a, then you will battle him, try to catch him, its your only chance to get a snorlax.
You need to get the kanto radio chip in your pokegear and go up to snorlax and put the dot right a the top and then talk to snorlax. P.S it is called pokemon heart gold
Snorlax does not evolve. In gold, it is a non-evolutionary pokemon.
go to the top line, near the right. there is a channel called pokeflute. with that on, go talk to snorlax's head. he will wake up and battle you. he has leftovers.
if your stuck in that part then the only way to get there is by goin to snorlax go to youtube to find out how to wake snorlax up and after that go in digglet tunnel thingie
