There is also usually a plot in a myth that tricks people into doing something.

A fairly is a wonder story about fairies. There is usually a protagonist, antagonist, problem, and solution in these stories. The antagonist usually does something bad and the protagonist resolves it. Sometimes, they’re from cultures, but mostly it’s not and made up to show things about how to act.
