This is Dave, AKA Chocolate Milk, the big black cow. One day, Dave was eating some fresh cut grass. When he looked up, he saw hills for miles and miles away. He realized he was all alone, and he got sad, so he began to sing "moo moo moo."
After he sang his song, he decided to go to Bethlehem to find friends. He had rainbow ice cream along the way, and began to sing his song again.
When he got to Bethlehem, he found his friends. They were so happy, that they all sang along together. "Moo moo moo!"
