Denver, the Last Dinosaur

It is late Spring when Wally, Jeremy, Shades and Mario are at the La Brea Tar Pits working on a school research project and discover a mysterious tar egg that cracks open to reveal a friendly dinosaur.

Denver follows Jeremy to his job at the supermarket, where he hides in the storeroom and stuffs himself full of potato chips.

Wally borrows his sister Heather's video camera and the starry-eyed kids set out to make a video starring themselves.

While camping at a mountain lake with the boys, Denver is mistaken for a horrible lake monster.

Denver and the kids make friends with a circus owner's son and help him liven up a lackluster show with bicycle and skateboard stunts.

The boys decide to do a science project on dinosaurs for the school science fair.

To help Wally in his predicament with Johnny Price, a practical joker who continually torments him, Denver uses his magic tar eggshell and shows Wally a time in his own life when he was tormented by the Pteranodon, and Wally is able to become friends with Johnny Price.

Decked out in caveman attire, Denver and the kids form a rock group (B.C. Rock) to compete in the city wide talent contest. Freddy Facknitts also form a group called Roborock (rock'n'roll robots). But Morton Fizzback and Dr. Funt steal the robot band right before the contest and the kids must go after them.
