"Packed with comics, diagrams, and "secret diaries," this book is a wondrous, encyclopedic glance at a dizzying host of different things--from hearts to farts to coconuts--and makes a hilarious and informative guide for curious young readers. Join the hilarious exploration of "a day in the life" of nearly 100 things on Earth. Find out what exactly your tongue does all day long, how a Japanese knotweed destroys everything in its path, and why no two snowflakes are ever the same. From the gross and smelly to the beautiful and fascinating, this book is a treasure trove of entertaining information."--Publisher's website.
