Scruffy was the fist living thing on Earth. He lived on this hill with a fence with nothing else. The sky was plain and blue. One day Scruffy realized how lonely he was and wanted create something more, so he barked into the sky and created sun and clouds.
Once he realized what he could do, he created a barn to live in and farmer to feed him.
He then realized that he needed friends to play with on the farm, so he barked up to the sky again and created a donkey, a pig, and a cow. Then he knew his world was complete.
