Old MacDino had a farm, E-I-E-I-O! And on this farm he had a...Stegosaurus! Old MacDino's farm is full of DINOSAURS! The cows, pigs, horses, and other animals are joined by a Diplodocus, a Triceratops, a Velociraptor, and more. With a Stomp! Stomp! here, and a Crash! Smash! there, they're causing chaos EVERYWHERE! What's a farmer to do?
