Donald's Duck

Donald's Duck is a Season 3 episode. Duck is working hard and Sir Topham Hatt gives him his own brachline like Thomas and Edward. A new station is being built on Duck's Branch Line, and Duck gets conceited. Donald tells him he 'quacks' like a duck, and he could lay an egg if he didn't be quiet. Duck gets angry, and he and his crew plan to pull a trick on Donald. The next day Donald finds a small duckling in his tender, and soon they become friends. But the other engines teased him about it, so he played a trick on Duck. Next morning Duck's driver and fireman find a box with an egg in it under Duck's bunker, and Duck apologises to Donald, after having a laugh. the duck now lives in a pond near the line, and is called 'Dilly' by the station master, but to everyone else, she is 'Donald's duck'.
