Starbeam is Dr. Stephen Colbert's unicorn friend. You cannot say that he owns Starbeam, as you cannot own unicorns. They are free and mysterious creatures that go wherever they please. You could sooner own a cloud or a rainbow. If you see Stephen's rainbow around somewhere, let him know. He misses it very much and would like it to come home.
Should another great flood occur, Stephen will save Starbeam from drowning, no matter the cost.
