Randomly placed duplicated MCs

I’m wondering if anyone has any ideas how I would go about having duplicated movie clips show up in random locations but along a drawing. I have a drawing and I want to randomly duplicate my MCs but have them be in random places along the outline of my drawing. They can be anywhere on that outside edge as long as they are right on the edge. Hope that was clear enough, anyone have any ideas how I would go about this?

Any ideas on how to do this?
