This story offers varied lessons. It portrays the senselessness of prejudice and discrimination, and also a lesson of materialism and entrepreneurship. Sneetches are a group of vaguely avian yellow creatures who live on a beach. Some Sneetches have a green star on their bellies, and in the beginning of the story the absence of a star is the basis for discrimination. Sneetches who have stars on their bellies are part of the "in crowd," while Sneetches without stars are shunned and consequently mopey.
