A zoo in Japan did an escaped animal drill recently and the video is pretty ridiculous.
Tobe Zoo in Ehime, Japan wanted to train staff for an escaped lion scenario. Obviously, it's not safe to release an actual lion and then try to recapture it.
Instead, a human in a lion costume was released and the security team was tasked to capture it.
The lion costume is better than a cheap Halloween costume but not as good as a minor league baseball team's mascot.
The video even shows the real lions react to the whole thing and their expression matched mine while watching it.
