What do worms do all day? How do they see? And why are they so cold and squishy? Find out by going on an underground tour through the hidden world of earthworms. Discover what's happening inside a worm's body—brain, crop, gizzard, and more. The book takes readers from "ew!" to "wow!" as they learn about the different ways worms work hard to help the earth.
