An Evanston Public Library Best Book of the Year " A light and lively education in the world of microorganisms ."- Publishers Weekly " Text, occasionally swirling across the pages, complements the playful illustrations to provide information in clear, child-friendly language . Soft, attractive pencil, watercolor, and mixed-media illustrations match well with the text, and their energy enhances the presentation. A useful, rather detailed glossary and a short essay on the value of hand-washing follow, although some listeners may wonder why anyone would want to wash away such cute little critters."- Kirkus Reviews "James Ransome's pencil and watercolor artwork is a strong complement to Sam's narration--capturing the tongue-in-cheek seriousness of a germ with an axe to grind, while fun-loving, multi-hued germs are just regular guys and gals trying to get on with their lives. Yes, you should wash your hands--but have a little remorse." - The Bulletin.
