When you are the size of Simon Small, everything else becomes very, very large. For example, an ordinary meatball becomes the size of a football and a jelly dish the size of a bath tub. Climbing onto a chair is like climbing to the top of a roof, and you really have to stretch to use a door handle. That is what life is like for pixies.
At Simon Small’s place, all children can find out what it is like to be a pixie. You just have to do what Bertil did in the story, the first time he had to pass through the rat hole down to Simon Small’s new home. Just touch the nail by the entrance and say “Killevippen”.This causes a normal-size person to shrink to the size of a pixie and can get through.
