Ten-year-old Michael Fogg has no imagination, and when he sees a tiny being standing on the landing outside Flat 4, he needs to pinch himself. Flat 4 has been empty for as long as he can remember and the sight of a strange old woman scolding him and accusing him of misbehaving when she has never met him before gives him quite a shock. He puts it out of his mind, but the next time he presses the button to turn on the stair lights there is another visitor looking up at him, This time it's a miniature man in a floppy hat. Doctor Fluff claims that he is from a land called Stutopia, where anything stupid is possible and when he offers to cure Michael's persistent hiccups he reluctantly agrees. One after another, wee folk and pygmy animals appear, each as weird as the last, all of them intent on curing Michael's hiccups with increasingly bizarre ideas. Michael's parents are baffled by his stories and think he must be teasing them. Finally Michael realises that the only way to convince them is for them to see the creatures for themselves...
