The popular author sets a predictable story among cavemen, adds dinosaurs, and terms the result a fairy tale--certainly a loose term at the best of times. The Grunts are expecting the Ugga-Wugga tribe for brunch, but what to feed them? Little Grunt brings home a giant egg, which won't do because it hatches. The resulting dinosaur, "George," doesn't make a good pet; but after being banished for being inconveniently huge, "he" returns to save the Grunts from an erupting volcano--and proves to be not George but Georgina. The illustrations are typical dePaola. The kids will lap it up, as they do TV cartoons of the same undemanding quality.
