Details

The least scary thing you’ll see this Halloween season

Leonardo is a terrible monster. He tries so hard to be scary, but he just…isn’t. But then he hatches a plan to find the most scaredy-cat kid in the world. Will Leonardo finally get to scare someone? Or will it be the start of an unlikely friendship?

This Halloween season, join Seattle Children’s Theatre for a not-very-spine-chilling, not-particularly-hair-raising, not-very-frightening-at-all-really romp with a monster. Based on the book by beloved author Mo Willems, Leonardo! A Wonderful Show about a Terrible Monster uses hundreds of puppets and props to bring Mo Willems’ books to life. Discover why making friends doesn’t have to be scary.
