How do you get the pokeflute on heartgold?

You can't get the Pokeflute in HeartGold. It was an item introduced in FireRed and LeafGreen to attract Snorlax.

In HeartGold, you need to use a different method to wake up Snorlax:

1. Find Snorlax: Snorlax is located in Goldenrod City's Pokemon Center on the second floor, sleeping in a room to the right.

2. Use a "Wake-Up Slap": Instead of a Pokeflute, you need to use a move like "Wake-Up Slap"** to wake up Snorlax.

3. Battle Snorlax: Once woken up, Snorlax will challenge you to a battle.

So, don't worry about finding a Pokeflute in HeartGold! The "Wake-Up Slap" method will do the trick for you.
