Publisher's Synopsis
One night, Spike creeps downstairs in his pyjamas to find that his granny has turned into a dinosaur, Grannysaurus. There are dinosaurs boogying in the living room. With Brontosaurus, Stegosaurus and Gigantosaurus, it's a dino disco. Spike wants to stay up and party too. How will Grannysaurus ever get him back to bed? Perhaps her next guest, Tyrannosaurus Rex, can help?
