For Bup the caveboy and his parents, life was just one unhappy prehistoric day after another. They were very good at hunting for food, pinching, shouting, and making grim faces, but they didn't know how to have fun. Then a wondrous creature with wiggly arms appeared and changed their dreary lives and the course of human history forever. This unique book features a die-cut cover, die-cut pages, foldouts, and cave talk that will tickle the funny bones of even the grumpiest readers.<br>
