Crikey the koala was just a baby when he was found all alone and very sick on Australia's Magnetic Island. But luckily for Crikey there's a remarkable family there who spend their time rescuing koalas and rehabilitating them in their home so that they can eventually go back to the wild. Ali Bee, a veterinarian with Magnetic Island Koala Hospital, and her family are fighting to save Australia's rapidly declining koala population. And she, her husband Tim, and their 10-year-old daughter Izzy, took Crikey in a year ago. Izzy became Crikey's surrogate mother and helped nurse him back to health. Now, the Bee family is preparing for the emotionally difficult but important and inspiring task of releasing Crickey back to his natural habitat. Saying goodbye won't be easy, for both Izzy and Crikey.
