Emily brings in a piece of cloth, which Charlie Mouse identifies as a house for a rag doll, leading to a several rag jokes from the mice! They fold up the cloth so that Bagpuss can use it as a thinking cap, and create the story of Uncle Feedle, which Gabriel and Madeleine sing along to.

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.
One dirty old shoe is left for Bagpuss and his friends to repair, and the mice suggest that it might be suitable for living in, which leads Madeleine to sing along with the mouse organ.

The mice run away, scared by the owl, but come back when they realise it isn't real...
Emily Brings home a bottle with some bits of wood in it. Professor Yaffle tells them it is a ship-in-a-bottle. Bagpuss finds this puzzling, wondering where it would sail to. With the help of a nursery rhyme and a poem about Mermaids, the ship is magically reassembled.
