Episode 8

There's an emergency at the primate enclosure - Gorbi the male drill has been losing weight and the vet needs to examine him immediately. The Javan langurs get a bungee jump to play with, but will they take the plunge? The green cat-eyed snakes need feeding and they're not ashamed of some seriously messy eating. Meanwhile, the gorillas - our closest animal relative - try to figure out how to undo simple screw caps.

Rani Price and Matthew Skilton bring more stories from the wild animal parks.
