You can paint spots, stripes and various patterns. The creature can call various battle and mating calls. You can test drive your creature and watch him spin, punch, roar , dance the Hippity Hop, Walk-In-Place, say “Ta-Dah” or show a range of happy to sad emotions. To watch your creature in action, you can rotate camera angles, add babies of your creation, and change the backdrops.
