Long, long ago, as a volcano erupts with a great roar and the ground below quakes, a baby ankylosaur hatches from his egg. As the little ankylosaur begins wandering about all by himself, a big, bruising tyrannosaur comes along. “Oh, yummy! Eh heh heh heh heh,” he exclaims in delight, and is about to pounce when the baby ankylosaur cries out, “Daddy!” and grabs onto his leg. In surprise, the tyrannosaur realizes that the little one has misunderstood and thinks he was being called “Yummy” as a name. And so it is that a tyrannosaur takes on the task of raising a baby ankylosaur. Yummy looks up to the tyrannosaur in everything he does, and says repeatedly, “I want to be just like you, Daddy!” Although the tyrannosaur feels a little guilty for hiding his real self and perpetuating a lie, the two develop ever stronger bonds of love. But then comes the day when they must part . . . The tale highlights the importance of family and of the love between parent and child by showing that bonds can grow just as strong even in a case of mistaken identity as they do between actual relations— possibly even stronger. The book is the first in a tremendously popular series featuring a tyrannosaur in 15 titles to date, with combined sales in excess of 15 million. In 2010 and 2015, the series became an animated film.
