One day Murrawar ran away and as she hurried along the beach, which was all flat in those days, she looked back and saw Burwilla's boomerang coming to kill her. Calling out for help, she fell to the ground too frightened to run. Suddenly she heard a loud noise in the sky and saw her faithful Rainbow racing towards her across the sea. The wicked boomerang attacked the brave Rainbow and they met with a roar like thunder, killing the boomerang instantly and shattering the Rainbow into many small pieces. Alas, the poor sick and shattered Rainbow lay on the beach to die and is still there with all its colours, forming the hills along the beach.
