What would a T.Rex write in his letter to Santa? Roar with laughter finding out! It's Christmas, and Max and his dinosaur friend are super-excited. (PS: to find out how this boy and this dino first met, read Dear Dinosaur.) They're busy putting up decorations, posting cards and-of course-writing letters to Santa. They're sure they've both been very good this year! But secretly, the T.Rex feels a little worried. Will Santa even deliver to a dinosaur?
