Emergencies are full of unknown factors that make safety drills seem irrelevant, but one Japanese zoo attempts to keep their staff on top of their game with an adorable, unique drill involving a man and a monkey suit.

A zoo at Ueno Park in Tokyo staged a simulated scenario involving an escaped gorilla after an earthquake. The drill involved a human outfitted with a gorilla costume escaping, a bit of net intimidation, some fake sedation, and subsequent capturing by the zoo staff.
