Generations of kids have interacted with lovable, furry old Grover as he begs the reader not to turn the page—for fear of a monster at the end of the book. Grover's antics and the interactive nature of the narrative invite children to engage with the story, building anticipation and humor with each page turn.

Grover's eventual realization that he himself is the 'monster' at the end of the book provides a delightful twist, teaching children about facing one's fears and the joy of self-discovery. The book's design and Grover's direct address to the reader make it a perfect choice for lap-time reading.

A big happy frog, a plump purple cat, a handsome blue horse, and a soft yellow duck—all parade across the pages of this delightful book. Children will immediately respond to Eric Carle's flat, boldly colored collages. Combined with Bill Martin's singsong text, they create unforgettable images of these endearing animals.
