Trixie, Daddy and Knuffle Bunny take a trip to the neighborhood Laundromat. But the exciting adventure takes a dramatic turn when Trixie realizes that "somebunny" has been left behind.... By combining expressive cartoon drawings with beautiful photographs of Brooklyn, New York, Mo Willems tells a brilliantly true-to-life tale about what happens when Daddy is in charge and things go terribly, hilariously, wrong.
