For those too young to remember
>Mr Ben 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 before the shopkeeper reappears to lead him back to the changing room, and the story comes to an end.
>At the end of each story, Mr Benn returns to his normal life, but is left with a small souvenir of his magical adventure. Additionally, scenes before and after his adventure
It doesn't say Mr Ben is a tragic no mates loser but it is implied through retreating into a fantasy world
