The adventures of Frank and Buster, two intrepid young koalas on a mission to help others in the outback. The duo get a letter from Penny, who has a problem - she can't knit. She wants to make a jumper for Lolly for the cold outback mornings. Wool is in short supply, but everyone gives Penny something, whether cotton, string or ribbon. Penny knits the bits and pieces together to make a distinctive scarf. Lolly is thrilled with her present, especially as it's one of a kind.
