Veneno para las hadas (Poison for the Fairies) is a 1984 Mexican supernatural horror film that was written and directed by Carlos Enrique Taboada.

Rather than being frightened, Veronica often comforts herself with these stories to feel more powerful than the girls at her parochial school, who mock and ostracize her for her strangeness.

Shortly thereafter, the piano teacher, who, unbeknownst to the children, suffers from a weak heart, collapses and dies, causing Flavia to believe they have murdered her.

When they are finally caught, Flavia blurts out their plans to her parents, who sternly chastise both girls and tell them that witches aren't real.
