The Love Monsters are nymphs which are female nature spirits from the Greek mythology.

They are fairy versions of the female students in the Torrington Academy, that became Love Monsters because of the Cursed Guitar in the episode Curse of the Six-String Serenade. The Love Monsters are desperately in love for Martin, as the Cursed Guitar makes all potential suitors fall in love with whoever plays it. However, they are turned back to normal at the end of the episode when Martin plays his song backwards on Torrington's PA system.
