Grandma tells Michael, Hannah, and their baby brother the story of three children who shrink to such a small size that they decide to live in a snail's shell.
John can do nothing well until a snail gives him one hundred fabulous stories to tell, but when even they wear thin, he goes in search of the snail again.
Photographs and text follow the life cycle of the snail from hatching to adulthood, and provide information about how the insects eat, mate, lay eggs, and grow shells.
