George the postman is persuaded by Mitzi to run a race with Archie, for the entertainment of the townsfolk. Archie, being very sporty and into keeping fit, is very confident, and feels sure he'll win. George asks the Koalas for some advice. They suggest that he just keep on going, whatever happens.
During the race Archie is a little too confident, and eats some of Alice's chocolate cake along the way, while George sticks to Frank's advice to just keep on going. Archie takes the opportunity to take a short nap under the tree at the waterhole to sleep off all the food he's eaten, but he oversleeps and George goes over the finish line first. Everyone learns that if you're persistent and dedicated, you can sometimes achieve amazing things.
