The Muppet Musicians of Bremen

In the Louisiana countryside, Kermit the Frog begins his narration with Mordecai Sledge and Leroy the Donkey, as they approach their residence after stealing items in a boxcar from a railroad yard. When they arrive, Mordecai finds the items are musical instruments, and blames Leroy for the items being worthless. He later scolds Leroy, and goes inside to find his shotgun so he can "retire" him. Startled by the gunshot, Leroy escapes from his owner with the tuba around his neck that Mordecai previously threw in a tree. Shortly after running, Leroy approaches Kermit who influences him to play the tuba, which inspires the donkey to become a traveling musician.
