Come Outside: Series 2: Stones

Auntie Mabel decides to build a rockery in her garden. She and Pippin fly off in their Spotty Plane in search of some stones. They visit a beach but the stones are too small for a rockery. So they go to a stone quarry where they see huge slabs of stone being dug out of the ground and watch the stone masons at work shaping pieces of stone which will be used to decorate the wall of a building. At the quarry Auntie Mabel finds some pieces of stone just the right size for the rockery.
