Underbelly Scales

I need some underbelly scales from black dragon whelps to pay for the shoes Argus sent me from Goldshire. If you can get 6 of them for me, then I can pay Argus with some... and have enough left to fashion something for you. Black dragon whelps are often flying around south of Lakeshire, but they like to wander. You might have to just keep an eye out and hunt them when you see them.
