They're going to discover Barney soon enough, if they haven't already, so parents may want to head them off at the pass with this cast of dinosaurs who are as diverse and rife with character as Barney is, well, purple. These dinosaurs, as colorfully and cleverly conceived by the Sticklands (The Christmas Bear, 1993), are huge but meek, tiny but fierce, clean but awfully prim, slovenly but affectionate. A ``sweet'' dinosaur tries to coyly ``hide'' behind a tree thinner than its arm; a ``fat'' dinosaur lounges with a palm tree between its fingers, about to chew it as if it were a blade of grass; in a primordial dinner scene, herbivores and carnivores alike look on in bemused astonishment as one strange creature, passing up both the foliage and the bones that are politely being consumed all around, feasts on the ``h'' in ``scrunch!'' Crafty details like these transform what might otherwise be just another look at the oldest cast of characters in children's literature into a visual extravaganza.
