I like the rhinoceros, its sharp horn and the armor-like skin, making it like a monster from the Middle Ages, like an armored car with four legs, really a cool animal. So the rhino became the first design in my Running Animals series. 【Running Animal Series】 The common feature of the works is that they can run down a slope of about 10 degrees, swing back and forth when running downhill, and make a ticking sound like a metronome. It looks very interesting. 【Running animal series】includes rhinoceros, polar bear, trisaurus, and brontosaurus.
