Diggory Digger and The Dinosaurs

Diggory and his faithful friend Morris the Mole have found a very mysterious tunnel and are itching to investigate. Down, down they go until they come across a rather stubborn boulder blocking their path...Then the boulder went Grunt! Then it srted and growled! Then it opened one eye, then ather and Howled! Diggory cried, 'That's boulder before us!' 'No!' squeaked the Mole. 'It's a - Diggerosaurus!'
