Lyle, Lyle Crocodile lives with the Primm family in the house on East 88th Street in New York City. Lyle enjoys helping with chores, playing with the neighborhood kids, and entertaining them with headstands and backflips. He’s the happiest crocodile any family ever had . . . until one neighbor insists that Lyle belongs in a zoo! Mr. Grumps and his cat, Loretta, don't like crocodiles, and everything Lyle does to win them over seems to go wrong. It will take all of Lyle’s charm—and courage—to reveal the hero, and friend, behind the big, crocodile smile.
