Mr. Benn

In this very first episode, Mr Benn has been invited to a fancy-dress party. He dislikes parties, but enjoys dressing up, so he looks round the shops for a costume to wear, but everywhere he finds only ordinary everyday clothes. Turning into a small lane on his way home, Mr Benn comes across a costume shop where he chooses an outfit of red knight's armour. Changing into the armour, Mr Benn passes through another door in the shop's changing room and finds himself in another world. He stumbles upon a dragon, and at first thinks it is someone else in fancy dress. He soon realises his mistake. He learns that the dragon used to be the King's pet, until an evil match-seller started a fire and made sure the dragon got the blame. Mr. Benn helps the dragon regain the King's favour. On returning to his own everyday world, Mr Benn decides he has had enough excitement and won't be going to the fancy-dress party after all. But he tells the shopkeeper that he will be coming back to the shop again soon to try another costume and have another adventure.,

Mr Benn is dressed as a hunter, in keeping with the pet shop and the garden centre he passed on his way to a shop. He doesn't behave like a hunter however.

They finally stumble upon a herd of elephants. Mr. Benn gets them to jump up and down, throwing the hunter off balance. He convinces the hunter to sell his rifle, buy a camera and become a wildlife photographer instead.
