Since Clefairy are quite hard to come by, they say that witnessing a ring of them dancing under a moonlit night is a sign of good things to come for those who see it. Because of their popularity with men and women and their penchant for bringing fortune, Clefairy owners should be careful of thieves.

They say that the areas where Clefairy gather together become enveloped in a magnetic field that is abnormal. The ability Magic Guard used to be exclusive to their line until Gen V and could be a reference to their overall mysteriously magical nature.
