It was a quiet day in the yard. I was enjoying a big mouthful of food, when something odd happened. A strange green ball floated over my head. There are different theories about what it might be. Some of my friends say it was a UFO. Others say it is a special food dispenser designed to give us some surprise treats. Either one is okay by me. I’m always up for surprise treats. On the other hand, I’ve always wanted to see a UFO.
