"Jake loves dinosaurs, so with his birthday coming up, he knows just what kind of party he wants -- a dinosaur sleepover! Dino games, dino balloons, dino cake, dino movies. Dino everything! But when the day of the party arrives his friends all come down with the flu, and the party seems to be on the edge of extinction. Then, in the middle of the night, Jake hears a strange noise and goes to investigate. To his surprise, he finds some new prehistoric party guests right there in his living room! The dinos have invited themselves in to make sure Jake has a birthday he'll never forget."-- Provided by publisher.
