Why This Method?
This technique is best suited for artwork more akin to “Adventure Time”, where the legs and arms are like tubes or spaghetti. It uses the puppet tool in AE. For an example of how to construct the artwork, download and take a look inside the Illustrator file, “beatnik.ai”. The download is zipped.
Here is a good tutorial from “Multimedia Production”.
