Ever since she averted disaster in the class production of The Wizard of Oz, Oddrey has been making new friends at school. Her classmates have come to appreciate her irrepressible charm and Oddrey, in turn, encourages them to be their own unique selves. So when Oddrey's teacher introduces a new girl, Maybelline, to the class, Oddrey, ever the optimist, is sure that they'll become the best of friends.

But Maybelline's elaborate storytelling habits and bossy playground personality soon force Oddrey to reconsider. Fed up with Maybelline's tall tales, and her classmates' fascination with Maybelline's stories, Oddrey challenges Maybelline during a class trip to the zoo. The adventure that ensues is Maybelline's — and Oddrey's — best adventure yet!
