Another charming and hilarious tale from Mo Willems! Leonardo is truly a terrible monster-terrible at being a monster that is. No matter how hard he tries, he can't seem to frighten anyone. Determined to succeed, Leonardo sets himself to training and research. Finally, he finds a nervous little boy, and scares the tuna salad out of him! But scaring people isn't quite as satisfying as he thought it would be. Leonardo realizes that he might be a terrible, awful monster-but he could be a really good friend. MO WILLEMS is the author of groundbreaking picture books, including: Knuffle Bunny: A Cautionary Tale (Caldecott Honor winner 2004); Don't Let the Pigeon Drive the Bus! (Caldecott Honor winner 2003); Time to Say "Please"!; Leonardo, the Terrible Monster; and Edwina, the Dinosaur Who Didn't Know She Was Extinct. In his previous life, Mo was a six-time Emmy Award winning writer and animator for Sesame Street and the creator of Cartoon Network's Sheep in the Big City. He lives with his family in Massachusetts.
