The story is about a cat named Zazar who is afraid of the dark and can't sleep at night. He asks Mr. Sun for help, who gives Zazar a sunbeam to use as a night light. The sunbeam breaks into sparkles that form stars. When the light from the stars is still not enough, Mr. Sun gives Zazar another sunbeam that he puts in a balloon. The balloon flies up and becomes Miss Moon, providing more light for Zazar at night so he is no longer afraid.
