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. Kevin McCloskey's book even shows readers what's happening inside a worm's body brain, crop, gizzard, and more. The book takes young readers from "ew!" to "wow!" as they learn about the different ways worms work hard to help the earth. Kids may pick up many of the life science lessons contained here on their first read, but they'll return to We Dig Worms! again and again to rediscover its story. Deceptively simple, humble yet charming, this little book reaches surprising depths . . . just like, well, a worm!
