Episode 3

Keepers are locked in a battle of wills with Dave the Canadian timber wolf, who keeps attempting to explore areas outside of his enclosure. Having worked at the park for 40 years, one keeper might have finally got the two grumpy hippos just where he wants them. Meanwhile, Jean discovers just how powerful an elephant sneeze really is. And as the sun sets on the lion paddock, keepers are rigging special cameras to try to discover what goes on after dark.
