I've been wanting to play with this rig for a while. Animated the body and feet, but I'm leaving the ears for last. I've done little hand drawn animations with a flour sac, but nothing in 3d. This rig is by a guy named Bill Ballout. I general, I'm pleased with how the flour sac moved; this is a great rig. However, he had some dynamics on it that drove me crazy. There was a jiggle on the body and a gravity effect on the ears. If you use this rig, just go into the hypergraph (connections) and delete that s***. Expressions and dynamics like that are fine for games, but they just screw up your senses if you're serious.
