Bagpuss

Season 1, Episode 5: The Hamish

Select Source

Nobody really knows what the floppy tartan cloth object that Emily has brought is, except Bagpuss. He says it is a small soft Hamish, a Highland beast that keeps its distance because it makes a terrible noise, like bagpipes played backwards. He tells a heart-rending story of Tavish McTavish, who also made a terrible noise, playing his bagpipes forwards, and his friendship with the Hamish.
