It's extremely rare for an animal to escape from its enclosure in a zoo, but staff have to know what to do if it ever did happen...
So Japan's Ueno Zoo has held a drill for its zookeepers.
But they didn't use a real zebra - one of their staff got dressed up as a zebra instead!
The fake zebra acted as if it had escaped after an earthquake and rushed past zoo staff. But they managed to catch the animal with a net ready to take it back to its enclosure.
