Sandmare is a horse drawn in the sand on a beach by a girl named Polly and her father. Pleased with their creation, Polly laments the inevitability of the Sandmare’s being washed away by the tide. But Polly makes a wish that the Sandmare could run free – and at the same time the Sandmare wishes herself, so the wish is very strong. After Polly has left, the Sandmare is able to stand up and run free. Now she must reach the stars, or at sunrise she will turn back into sand.
