Set at a time "before many of us were born", we visit the home of the hungry "Casper Caveman" who wakes up and with his pet dinosaur "Fido" and sets off to find food. Meantime, "Daffy" is idly paddling in his pond and is soon - well, on the menu. Loads of quickly paced antics, and some fun sound effects follow as possibly the dumbest dinosaur/caveman combo try to ensnare our hero. Loads of fine Dvorak, Mendelssohn and even some Harry Warren keep it entertaining, too!...
