Never dance with a dinosaur

Toby loves to dance. Especially wiggling and whirling, spinning and stamping, jumping and jiving, and twisting and tumbling. His dance teacher says they should imagine dancing with a beautiful creature. So Toby imagines stomping round with a dinosaur. But then the dinosaur ACTUALLY appears - and he and Toby waltz and boogie and tango their way round the town. Nothing can go wrong there. Can it?
