Well, the first thing to ask is whether this "sock monkey" has groups? I could not find the object. If it has the groups and is not just one mesh object - you should be able to find instructions looking for PHI. This is a text file that sets up the movement dependencies (to best of my knowledge). Like if body moves forward then hand moves with it (z trans) or if hand moves up (y trans) forearm, etc moves up too. If it doesnt have groups - believe that you have to create them with the grouping tool but not sure as only have done the "bone" creations in PPP and P5. Good luck! PS this is a "to my knowledge post" ;-)
