A training drill at a Japanese zoo uses a life-size papier-mâché rhinoceros to simulate an animal escape and rescue, complete with paper tranquilizer darts. This video from Diagonal View is from 2008, but the story recently went viral again after The Telegraph covered it in this video. Apparently, the drills are an annual practice.
