Get ready for a new kind superhero--a smelly one! An eleven-year-old boy with the power of super smelly farts and his new dog sidekick team up to defeat an evil alien scientist before he takes over the world! From New York Times bestselling author of Mighty Dads. One day at P.U. Smellamentary, a regular kid named Phartolomew discovers his farts are super strong... strong enough to blow away some bad guys! But that's not the only thing he discovers! He finds a hidden lab in the school basement that belongs to the nefarious Professor Gravypants, the evil alien scientist who created him. When the professor's former minion Reeky Dog reveals that the Professor Gravypants is getting ready for world domination, Phartolomew decides to team up with newly-good Reeky Dog and use his fart powers for good. With his new alien friend Reeky Dog by his side, Phartolomew is on a mission--to stink up Professor Gravypants's evil plans to take over the world by becoming a new superhero called Fart Boy! New York Times bestselling author Joan Holub teams up with celebrated cartoonist Rafael Rosado to create a hilarious (and odorous) new superhero tale.
