- “"It makes me proud to be an excavator!"”
Thomas takes the Fat Controller to see the site for the new school the Pack are preparing. After the Fat Controller leaves, Max tells Oliver to hurry up, but he takes no notice. However, his bucket hits something hard buried in the ground. Oliver's operator suggests that it could be important, so the Foreman calls Miss Jenny, who calls the Fat Controller, who calls the Experts. The Experts realise that Oliver has discovered a dinosaur bone. Using his chisel, Oliver digs away more earth to uncover a complete dinosaur skeleton. A photographer takes a picture of Oliver with the dinosaur and the following day, Thomas brings the Fat Controller, who shows the Pack that Oliver is on the front page of the Sodor Times with the headline: "Digger Digs Dino!"
