K-Gr 4-Buzz Beaker, boy scientist extraordinaire, has met a challenge that can't be resolved with his microscope. Her name is Sarah Bellum, "Certified girl genius. With an IQ of 187.6." Then her extra-extra credit project-the cosmic copier-backfires and fills the school with over a thousand "copies" of her pet bat, Bobo. Yes, Sarah has made a "boo-boo with Bobo." Only Buzz can save the day. Cartoon cells frame Buzz's world. Subtle color shading brings depth to digitally finished illustrations and draws readers beyond the confines of the frames to enhance both the comic expressions and the action of the text. Zany art; engaging characters with exaggerated, off-center features; and a problem to solve make this great fun for the younger set as well as reluctant readers.-Mary Elam, Forman Elementary School, Plano, TX Copyright 2007 Reed Business Information.
