Plot
Trixie Willems and her family take a trip to visit her grandparents in Holland. She accidentally leaves her beloved stuffed toy rabbit, Knuffle Bunny, on the airplane and does not realize the toy bunny is missing — until it is too late. Knuffle Bunny is on his way to China. Trixie's family reassures her that she is getting older, so she must try to have courage. Still sad, Trixie goes to bed. She dreams of all the fantastic places Knuffle Bunny will visit and all of the fun things he will do. This brightens her mood considerably and comforts her. Soon, her vacation is over, and she gets on the airplane to fly back home to New York City. Surprisingly, it is the same plane as before, and Knuffle Bunny is waiting for her in a seat pocket. Trixie is excited until she sees a baby crying on the airplane and gives Knuffle Bunny to the baby for comfort.

Epilogue
In an epilogue to the book, Mo Willems wishes the real Trixie, his daughter, a happy and fulfilling life, and he predicts that Knuffle Bunny will someday return as a playmate for his daughter's own child.

Reception
Knuffle Bunny Free was received well by critics. In The New York Times, the American columnist Pamela Paul stated that the book "will leave children aspiring to be like its hero or proud that they already are."

For his work on the book, Willems was a finalist of the 2011 Children's Book Week Illustrator of the Year (sponsored by the Children's Book Council of the United States).
