There is a crisis in Koala Creek as the vet team is called in to investigate why Violet is struggling with her breathing. Ben Fogle and Kate Humble report on how she’s battled with her health since she first arrived from Australia just a few months ago. But could this latest battle be one too many for Violet, or will she pull through? In the wild, skunks and north American tree porcupines rub along quite nicely together. But what happens when porcupine Parsnip, bristling with killer quills, comes face to face for the very first time with Cecil the skunk, who will unleash one of the smelliest stinks in the animal world if he gets upset? Who will come off worst? Or will it be the keepers in the firing line? Kate discovers how the death of southern koala Wilpena, just weeks after arriving at the park, might not have been in vain. Wilpena is helping scientists make a breakthrough in understanding why certain diseases are endemic in these vulnerable creatures, and thanks to her a cure might now not be too far away. Jean Johansson discovers how keepers keep tamarin monkeys from straying too far from home.
