The Cretaceous era is long past, but T-Rex returns, accompanied by She-Rex and their comparatively tiny offspring, Wee-Rex. In Hugh Murphy's third book of sly cartoons, the super-predator does his best in a world made for creatures with smaller heads and longer arms. Just try not to chortle as the king of the dinosaurs attempts to play tennis, hail a cab, shear a flock of sheep, and get a basketball out from under the car.
