Book excerpt: Does the egg lying in the golden sand belong to a penguin or a turtle, a snake or a butterfly? Use what you already know about animals and their environments along with the illustrative evidence that Guy Troughton provides to sleuth around and predict which animal will hatch from which egg. Let Whose Egg? aid the imagination in visualizing everything from emerald green eggs to those that house “scaly claws” and “snapping jaws.” Kids will love opening up the flaps and discovering what type of animal belongs to each egg.
