Read the excerpt from a short story. The beach teemed with tourists from boardwalk to shore. A canopy of colorful umbrellas covered the sand. Each was preoccupied with his own happy task, and none noticed the figure as it emerged from the surf. Its skin was blistered and raw, and it lumbered awkwardly in the foam. Its hideous eyes hungrily appraised the masses. How does the excerpt exemplify the ideas King describes in "Danse Macabre"?
