PreS-Gr 1 This is a fun, absurd tale about two children with big imaginations. Joe and his sister Sally follow what they believe to be dinosaur footprints. A thought bubble shows what Sally imagines the source of the footprints to look like, and as the children uncover more information about their dinosaur, the image morphs and grows to reflect their findings. Finally, the children set a trap for the "hungry, heavy, swimming, dancing dinosaur with a headache and a sore foot." Only, it may not be the best idea to follow and trap a hungry dinosaur. Illustrations are digitized pencil drawings, and the large, colorful backgrounds make Sally's thought bubbles stand out and help draw attention to just how big a thing an imagination can be. VERDICT A general purchase where dinosaurs, silly stories, and books about imaginative play are popular. Kelly Roth, Bartow County Public Library, Cartersville, GA
