Daria has a top-secret problem: she’s been hiding real, live dinosaurs in her bedroom!

But when the dinos start multiplying, her room turns into a full-blown dino disaster zone. Things get even worse when her grandmother accidentally leaves the window open… and the dinosaurs escape into the world outside!

Now, with the help of her friends Oleg and Rory, Daria must race against time to launch Operation: Hide the Dinos. Can they round up the runaway reptiles before anyone discovers their roar-some secret?
