Mo Willems is best known for his No. 1 New York Times best-selling picture books, which have been awarded three Caldecott Honors ("Knuffle Bunny," "Knuffle Bunny Too" and "Don't Let the Pigeon Drive the Bus!"), two Theodor Geisel Medals, and five Geisel Honors (The "Elephant & Piggie" series).


Leonardo is a terrible monster. He tries so hard to be scary, but he just…isn’t. Then Leonardo finds Sam, the most scaredy-cat kid in the world. Will Leonardo finally get to scare the tuna salad out of someone? Or will it be the start of an unlikely friendship? The plot thickens when the pair meets Kerry and Frankenthaler, an even scaredier-cat and her monster friend. Kerry and Sam need to make a big decision: Will they just be scaredy-cats or can they become friends?

“Leonardo! A Wonderful Show About a Terrible Monster” uses hundreds of illustrated paper puppets, book pages, two-dimensional props, furry monster puppets and songs to bring Mo Willems’ books to life. Calling on the playful use of scale, Manual Cinema has recreated the experience of holding one of Mo’s big, bold, colorful books, full of visual rhythm. Like all Manual Cinema productions, you’re invited to watch the big screen like a traditional movie or watch the artists below it as they create the story in real time. (There is no wrong way to watch the show!)
