Even zoos have to prepare for worst-case-scenarios, like when an animal escapes its enclosure. But I'm not so sure the paper mache rhinoceros used at the Ueno Zoo in Tokyo really drives the point home of how dangerous this could be.

I doubt a wall of nets is going to deter it from charging, nor do I think that team of volunteers is going to stick around to hold them up. Particularly after witnessing a zoo keeper being gored to death. But one thing's for certain, the zoo's Cinco de Mayo celebration this year is going to be great.
