Rhinoceros

Rhino is a vector based animal character with Spring Bones and 360 Head capability. 
FREE TRIAL is available, so you can download and test it before you would purchase it.

Features:

• G3 Character
• Vector Scaling
• Spring Bones
• Lip Synching
• Facial Puppetry and Morph

I recommend to apply horse motions for the best animation result, but other quadruped motions can also fit.
