Every year, the Ueno Zoo in Tokyo holds a drill in case the animals escape.
Only instead of practicing with the real thing, workers wear costumes.
This year's practice run involved a zebra startled by an earthquake.
As part of the drill, guests were evacuated, injuries were treated and the zebra was "subdued" with a stun gun.
In the past, the zoo has practiced captures for fake rhinos, gorillas, lions and more.
