At the brand-new Dino Park, Bob, Scoop, Muck and Lofty are all ready for the arrival of the model dinosaurs. The team must get them into position ready for Mayor Madison, who is coming to inspect the Dino Park before opening it to the public. Muck is nervous though; the dinosaur models seem very realistic, and they can even roar! When Scoop and Lofty decide to play a trick on Muck, it seems like the dinosaurs have come to life - but have they given Muck too much of a fright, and will Bob and the team be able to put the Dino-Park back together in time for Mayor Madison?
