Nilly (short for nearly invisible) is the new kid at school and he quickly makes friends with the weirdest old man on the street, Dr. Proctor. Dr. Proctor is an inventor of (mostly) useless things and his latest invention needs a test subject. Nilly agrees and he, Nilly's friend Lisa, and Dr. Proctor begin work on perfecting the Fart Powder. It's amazing! It makes you fart but not stink! When the school bullies hear about the fart powder, they want it for themselves and Nilly, Lisa and the Doctor are going to have to figure out how to keep it safe! Filled with cute illustrations, this book will keep you laughing!
