Normally, Penny, the little Pea princess, doesn?t like to go to bed but today she is very tired. To make sure she gets a good night?s sleep, Penny stacks a high tower of mattresses, down comforters and pillows on top of each other in her bed. Oh so soft, but oh so wobbly! Who can help Penny, stack her pillows, down comforters and mattresses so she can finally, happily fall sleep?
