In Series 2, Episode 35 – 'The Sport of Kings', Skippy and Sonny are at the racetrack to watch Mark Hammond compete. After Sonny explains the process of betting to Skippy, the clever kangaroo places a $1 bet on a horse called Wallaby Bill.
Not surprisingly, Wallaby Bill wins the race and Skippy collects her winnings from the bookmaker.
This is a good example of a scene where Skippy is shown to possess remarkable abilities beyond those of a regular kangaroo. While her exploits may stretch the limits of credulity, they are also one of the ingredients of the show's success and why it was so beloved by audiences worldwide.
