Five children and it

Its eyes were on long horns like a snail's eyes. it had ears like a bat's ears, and its tubby body was shaped like a spider's and covered with thick, soft fur. and it had hands and feet like a monkey's. 'It' was the Psammead, the grumpy sand-fairy that could, if in the mood, grant a wish a day. When the five children befriend him they find that each wish granted often has a sting in its tail. Golden guineas are too difficult to spend, wings let them down in a most inconvenient way, and when they wish for Red Indians, the children forget that they can sometimes be a little warlike. Generations of children have come to love the fantasy and the whimsy of the stories in the classic book from the author of The Railway Children.
