Indigo

Big Bird figures he can cheer him up by shouting "Seventy-Six Trombones" in his face, until Bob suggests something more soothing and sings "Sing, Little Bluebird." With a little help, Indigo begins to chirp along, but never speaks. The puppet was mostly used as a background extra, often appearing with other birds for musical numbers. video as the Blue-Feathered Swallowing Swallow.
