Jack and his pet dino-dog get up early each morning to tend to the duties of the dinosaur farm. First the pterodactyl eggs need collecting. Then the tricerotops need to be let out to graze. Of course the diplodocus need a good scrub after their mud bath...they do get very messy! Exhausted after his daily chores, Jack collapses into bed. But wait! Did he close the gate to the T-Rex pen?
