The Dinosaur that Pooped a Reindeer, by Tom Fletcher & Dougie Poynter

One Christmas Eve, Danny and Dino receive an exciting invitation to the North Pole. Soon, they're on a festive tour of Santa's workshop, meeting elves and reindeer along the way. There's just one problem - Dino is VERY hungry, and he's surrounded by treats! Will he hold off until Santa's special feast, or will his rumbly tummy ruin Christmas?
