Shaped, die-cut, picture-changing pages add in interactive element-say Night, night and turn the page to watch the trucks transform from being awake to asleep. Say goodnight to the digger, the pick-up truck, and all their truck friends, as you turn the shaped pages and watch as the trucks go to sleep, one by one. Beautifully illustrated in soft, night-time tones. Magical sky of glow-in-the-dark stars on the final spread. Part of a best selling series.
