Level 3. Pearl and Wagner are two good friends who make a trash-eating robot together, impress a judge at the science fair, and tell each other the truth (even when it hurts!). They may be two very different individuals - Pearl, a hardworking rabbit and Wagner, a daydreaming mouse - but they know how to make up and stay good friends no matter what. This easy-to-read book is the first book in the Theodor Seuss Geisel Honor-winning Pearl and Wagner series.
