Footage captured at a Japan’s Tobe Zoo shows a human dressed up in a lion costume during a drill. In the background, the real lions watch the charade looking deeply unimpressed. The elaborate drills are common in Japan, where escapes by a polar bear, a leopard and even a rhino have all been staged. The earthquake-prone country performs the drills, which end with the animal being tranquillised, in case a natural disaster leaves animal enclosures and a real lion on the run.
