Perhaps it's because he knows that a Triceratops is a plant eater.  But you can't say that about the hungry meat eater you  saw on the page before this one!  Surely the boy can't be smiling because he's trapped in a twisted oozing molten lava cave with the last famished remnants of the dinosaur age, can he?  The dinosaurs escaped there with him when the giant meteor struck the earth - plunging the planet into chaos and an unstoppable ice age, and now there's no turning back.  Boys and girls, the cave is dark, and the only light comes from the glowing red molten lava breaking its way through the craggy walls of the twisted and awe inspiring dinosaur cave.  Will you dare to go inside?  And if you come out, will your smile also be - frozen in time?  What secrets will you discover inside...
Why is the Boy Smiling?!?
