This gorgeously gross interactive book is packed with fun facts on farts, snot, vomit, wee, spit and more bodily excretions! Find out how much snot we swallow in a year, how many times we fart in a lifetime, and whether it's really true that some people use urine as a mouthwash. With foul-fact-ridden text, drippingly disgusting artwork and noxious novelties, this book will fascinate those with a taste for all things yucky!
