Snake Crawl Using Bones Anime Studio Pro Tutorial

I saw this idea posted on the lost marble forum, and though it would do a great tutorial.Create a snake, moving, following a path, by using bones on Anime Studio Pro 5. you must to create several horizontal bones, no one child of another, all parents. then in frame one rotate them to create the path. The snake layer (a vector layer inside the bone layer) must be moved from one extreme of the bone chain to the other. The body has to have several points to move smoothly.
