Our daughter found this book in the reading area of the science museum. After our initial reading she promptly asked for it to be read to her again and again! An Extraordinary Egg is a story of a most unlikely friendship. When Jessica the frog brings back home what she thinks is a stone, Marilyn the frog quickly announces with authority that Jessica has found a chicken egg not a stone. Before long an alligator hatches from the egg. The frogs are excited by the swimming skills of the “chicken” and delight in swimming and playing in the water together. One day Jessica become tangled in some weeds and the “chicken” saves her. From that point forward the two are inseparable friends. Ultimately, the “chicken” finds his way back to his mother, and the frogs find it tremendously silly that the “chicken’s” mother calls her baby her “sweet little alligator”.
