The Luna Moths are Luna Girl's minions (and possibly the only friends she has), and vigilante counterparts of the Papinuits. They serve as the secondary sidekicks in PJ Masks series.
On some occasions, the moths can unite to carry Luna Girl around by flight when she doesn't use her Luna Board. In certain situations, they attempt to warn Luna Girl of impending misfortune, even though she tends to ignore them. They also have the ability to make noise to mimic human language and sometimes communicate with Luna Girl.
They follow all of Luna Girl's orders and attempt to complete them to the best of their ability. The moths love her, despite her often mean and verbally-abusive treatment to them.
The moths are identical to the papinuits, except that they're turquoise in color, have black eyes in color as they lack eye pupils, and their mouth is not visible. They can also be large when flying in groups.
