A new egg has just arrived, and Little Pip's parents are so excited! They tell Pip that this new change will soon make their family "just right"—but Little Pip isn't so sure. She thinks their family is already just right, and a boring old egg certainly can't make it any better! It seems to Pip that all anyone cares about is that EGG. Pip soon learns to help as much as she can, and through the long, harsh winter, she and Papa guard the egg, keeping it warm. But she still can't figure what all the fuss is about... until the day when CRACK! the egg breaks open and Pip joyfully meets her baby brother Sam for the very first time!
