The creators of "Bat Jamboree," which "School Library Journal" called "a witty combination of counting book and theatrical experience," are proud to introduce -- 385 marching band bats!From the drum majorette, who marches 1 X 1, to the sousaphones striding 10 X 10, these bats march in multiples to the tune of Kathi Appelt's snappy text and Melissa Sweet's boisterous illustrations.
