Rhino Rig!
Here it is! I cleaned it up a bit for you guys. The Rig is just joints with skin weights ( who needs controls? am I right? )
RhinoRig.zip (5.1 MB)
Clips_Textures.zip (3.6 MB)
There are 2 animation clips in there that you can load through the time editor.
Have fun stampeding 
Any questions, please reply in this thread .
