“If you love fantasy, funny humor, flatulence, and friends, then Aaron Reynolds has written the perfect book for you!” —DAN SANTAT, author of The Aquanut, Sidekicks, and The Adventures of Beekle

Another fart-tastic installment in the middle-grade adventure series by #1 New York Times bestselling author Aaron Reynolds and illustrator Cam Kendell.

The Great and Powerful Kevin has a new quest for our heroes... seek out another disgusting ingredient for his mysterious project.

High in the Frostflung Mountains lies the lair of a fearsome dragon named Glacierbane. Pan, Moxie, Fart and TickTock must venture there and fish a dragon-digested object from deep within a pile of dragon doo.

But Pan isn’t having it. She’s not sure why, but she doesn’t trust Kevin. But when she learns of a kidnapped prince that needs rescuing from Glacierbane, suddenly this quest seems a whole lot more heroic.

Our young heroes will face their toughest challenges yet as they team up with a valiant knight, brave the air-islands of Frostflung, fight yetis and snow goblins, solve puzzles and riddles, face a dragon, and seek the poo they need.
