The harmless hognose snake is a champion bluffer. When this snake is threatened, it hisses and acts as if it will bite. If you don't run away, the hognose snake "plays dead." It rolls over on its back, wiggling around as if it's in distress. Then it "dies" with its mouth open and tongue hanging out. If you turn it on its stomach, the snake will roll over on its back again.
