You can fake some softbody stuff. Add a magnet to your figures body, open the Add Element to Deform and add all the body groups you want to be effected. Then just parent the magnet to a finger and scale the mag zone down. Now all you have to do is run the finger anywhere you want and it fakes the softbody look.

I learned that one in 2002 here fom a thread that does not seem to be anymore. There is a newer one that claims the discovery. That's poserdom. LOL
