The Koala Brothers

The adventures of Frank and Buster, two intrepid young koalas who fly around the Australian outback in their yellow plane, on a special mission to help other creatures in need. Ned feels left out as he can't whistle. He returns to his caravan for some tea, but finds even the kettle can whistle! The Koalas discover that Ned whistles when he snores. Frank organises a tea party and gets everyone to make a particular noise. He asks Ned to snore, who realises he had a whistle inside him all along.
