List of The Worst Witch characters
Mildred Hubble is the titular character of "The Worst Witch" series. Unlike the other girls at Miss Cackle's Academy for Witches, she doesn't come from a regular witch family, but was given a scholarship which greatly impressed Miss Cackle. She is best friends with Maud Spellbody and Enid Nightshade. In "The Worst Witch", although inadvertently ruining a broomstick formation flying display when she was given a sabotaged broomstick, she saves the whole academy from Miss Cackle's jealous and rebel-ish identical twin sister Agatha Cackle, who was seeking to turn all the teachers and pupils into frogs. In the nick of time, Mildred turns Agatha and the rest of her fiendish coven into snails.
List of minor The Worst Witch characters
Miss Mould is an art teacher who is friendlier than Miss Hardbroom. She uses a lot of flowery language and can be quite melodramatic, telling the girls to "be one with the clay" and "get it under your fingernails". Miss Mould is also a very responsible and protective teacher, as seen when Mildred's pot turns into five rattlesnakes (later revealed to have been done by Ethel Hallow) when she springs into action and manages to get all of the girls out of the classroom.
