Nia teaches children about the microorganisms that can make them sick! And shows them how to get rid of them! Nia the Germinator doesn't have human brothers but she does have four very irritating very messy, very tiny brothers that live in her house. They are the germ brothers...Backy, Fungy, Vick and Protee (well, that's what she calls them!) Every Saturday it is house cleaning day and she goes to war with them! Nia the Germinator explains the everyday germs that live with us and how cool cleaning can be!
