The adventures of Frank and Buster, two intrepid young koalas on a mission to help other creatures in the Australian outback. Frank and Buster meet a little penguin backpacker who has run out of water.
They take her back to their house and give her food and water. After taking some group photos, the koalas are sad that their new friend has to leave. Later, they receive a package from their penguin friend in Antarctica and are glad that they will be able to stay in touch.
