Bea often tells little fibs when something goes wrong. And lately, a humongous Yeticorn has been charging around, gobbling up her sister Edie's sweets and sneezing confetti everywhere! But one day, Bea wakes to find that a Yeticorn REALLY has come to stay - and his whippy, trippy tail causes all sorts of problems that she gets the blame for! Can Bea find the courage to stop fibbing and finally tell the truth? 3+ From the author of 'How to Grow a Unicorn'.
