I can't find any Heart Scales. According to my Game Guide, I can Find them by using "Rock Smash", or Receive it as a Pokethon Prize on Wednesday. I tried using "Rock Smash" and Yet all I found were Krabby, Shuckle, Geodude, Graveler, and some colored shards, but NO Heart Scales. Plus the chances of winning that item at a pokethon is pretty slim. What's the easiest way to obtain heart scales in Heart Gold and Soul Silver?
