Carbon Costume

Mr Benn is the title character of both the book and the television series. In each book/episode he visits a local fancy dress shop run by a guy only known as the Shopkeeper, picks a costume and uses a magic door to go on an adventure.

Mr Benn, a man wearing a black suit and bowler hat who never seems to go to work, leaves his house at 52 Festive Road and visits a fancy-dress costume shop where he is invited by the moustachioed, fez-wearing shopkeeper to try on a particular outfit.

He leaves the shop through a magic door at the back of the changing room and enters a world appropriate to his costume, where he has an adventure (which usually contains a moral) before the shopkeeper re-appears to lead him back to the changing room, and the story comes to an end. Mr Benn returns to his normal life, but is left with a small souvenir of his magical adventure.
