In search of some experience inside their own safe and peaceful valley, the five dinosaur friends make a hide away. From there, they spot just two thieves in actions, concealing an egg. They manage to recoup the egg without its parents detecting and chase down them, in the practice, inadvertently make an opening into the valley, even allowing two Sharptooths that is dreaded in. Every one must fight off them together to preserve their peaceful means of life. Written by Cynan Rees
