Prehistoric Blue. Shovel and Pail find dinosaur footprints in the backyard, leading Shovel to worry that dinosaurs might be lurking in the backyard, despite Pail's assurances that they became extinct millions of years ago. We help to calm Shovel's fears by identifying the real animals that are in the backyard. We have fun with Steve pretending to be dinosaurs, learning, among other things, the difference between meat-eaters and plant-eaters. In the Blue Skidoo segment, we actually head back in time and find out about a number of dinosaurs, from what they looked like to how they behaved.
