So I had some time tonight and decided to see what the problem with La Femme is in Bullet Physics. I selected Bullet Physics and opened it up. I only had two objects in the scene. La Femme and the Ground. The Ground went under Choreographed. Ground ALWAYS go under Choreographed. it doesn't do anything and it's not supposed to move. La Femme went under soft bodies. Make sure you check the box to add her to that group. Next I made sure that La Femme was listed in the objects in the scene. and I clicked on Live Simulation. She collapsed into a puddle of goo. Now, assuming you want certain parts of her to "jiggle" or bounce when she walks, you'll need to expand the Hierarchy editor and select that body part to work on. Then you'll probably have to experiment a little to find the right settings. I rarely use Bullet Physics and don't really make breasts jiggle at all, so I couldn't tell you what those settings are.
