You never know what will happen when a T. Rex crashes your birthday party. Sure, you'll be super excited when he turns up at your door. But then he'll stomp. He'll Roar. He'll look at you as if he's wondering how you taste with a little mustard. In the end, though, you just may find yourself asking him to come back next year! This delightfully whimsical picture book has a fun twist kids will love.
