There was a deep, low grumbling, groaning noise coming from deep within the forest where no grumbling, groaning noise should be heard. Sagebrush, the tailless puppy, felt the vibration of the earth before she heard the noise as the sun began to rise over the Rocky Mountains and the cattle ranch she called home. Sagebrush journeys into the deepest recesses of the forest, discovering the tiny unknown creatures called Shuns, who are now homeless due to the giant tree-cutting machines that the humans have sent to clear the forest of the trees that the Shuns once made their homes in.
