Trixie can't wait to bring her one-of-a-kind Knuffle Bunny to school and show him off to everyone. But when she gets there, she sees something awful: Sonja has the same bunny. Suddenly, Knuffle Bunny doesn't seem so one-of-a-kind anymore. Chaos ensues until the bunnies are taken away by Ms. Greengrove. After school, Trixie finally gets her beloved bunny back. But in the middle of the night, Trixie realizes something. She has the wrong bunny! Daddy comes to the rescue again as a midnight swap is arranged with the other bunny, the other little girl, and the other daddy. Needless to say, the daddies are not very happy. By the end of the story Trixie has her beloved bunny back, but she has also gained something new: her very first best friend. In the tradition of the Caldecott Honor-winner Knuffle Bunny: A Cautionary Tale , this is another heartfelt, hilarious picture book that children (and their parents) will love.
