Duncan and the Hot Air Balloon

Duncan and the Hot Air Balloon is a twelfth season episode.

Plot
Duncan is disappointed to learn that, instead of taking the Percival twins on a special train ride for their birthday, they will be having a ride in the Hot Air Balloon. When Duncan collects the balloon, he is told to go carefully, but when he comes across some bumpy track the balloon becomes untethered. Duncan slyly bangs into the balloon, causing it to float away. However, when the weathervane on Mr. Percival's house tears a hole in the balloon, Duncan sees the error of his ways and owns up to Mr. Percival. Duncan collects the balloon repair man, who has little hope of repairing the balloon until Duncan suggests using his birthday flag.
