In Pokémon HeartGold, the Heart Scale is the item that you give to the Move Reminder in Blackthorn City. The Reminder will assist your Pokémon in remembering any moves that it previously learned via level-up in its current state whether it missed them because of evolving late or it just forgot them for newer moves.

Underground. You have to dig at dig spots to find them, among other things.
Every Sunday and Wednesday at the Pokeathlon Dome you can buy a Heartscale for 1000 Points. Or Rock Smash some rocks at Kanto or Johto. Or you can go to Vermillion city in Kanto.Use your Dowsing machine near the boats. Use surf to get to one of them and it is on the side of the boat. hope this helps:-)
None of the Pokemon do, silly! :D you get the heartscale by digging it from the underground. (be careful, their small!! if you go to pastoria, there is a guy who will teach your Pokemon a forgotten move if you give him a heartscale. his house is next to the lake.) *hope this helped*
Dig for it underground. Its rare but it is possible to dig one up
You can find them on Luvdisks in Pokemon Emrald and Ruby and Sapphire, and you find them underground in Pokemon diamond
