Day 500: Today, they let me out. I discovered I was being held captive by unicorns who were trying to figure out what I was
Day 501: The Unicorns had a picnic with me and are building me a ship to get back to Earth.
Day 502: I hugged all of the unicorns and said goodbye as I blasted off back to Earth
Day 503: I am finally back. I am happy it is all over. :)
