The Worst Witch
Miss Cackle has an evil twin sister named Agatha Cackle, who is bitterly jealous of her position of authority at the Academy. In the first of the series, Agatha and her coven of rebellious witches plotted to overthrow Miss Cackle and turn her, the staff, and students into frogs as they slept. Mildred caught them as they brewed their invisibility potion, by turning them into snails and taking them to the school to show Miss Cackle. Ashamed that her own sister would break the Witches' Code, she ordered Agatha to accept defeat and live the code like all decent witches. Agatha reluctantly co-operated. She tries to take over again at the end of series 1, by pretending to be Miss Cackle and dragging Mildred out of the classroom by her ear.
