Gr 1–2—Cork is a short muskrat with patience and willingness to try new things, while Fuzz, a tall possum, does not like to wait for anything and is often less than enthusiastic when adventures present themselves. They are like The Odd Couple of the animal world—one sloppy, one striving to keep everything in perfect order. In this four-chapter, easy-to-read story, they prove that best friends with many differences can have fun together. This series installment offers familiar characters with plenty of dialogue and a story line with more twists and turns to encourage readers' growth. The balance of text and art is just right, and the bright illustrations show these friends working out their differences. Suggested activities help children understand the feelings of the characters and explore their own characteristics. VERDICT A solid addition to a well-established series.—Janene Corbin, Rosebank Elementary School, Nashville, TN
