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 housecleaning 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!
