The Worst Witch is a series of children's books written and illustrated by Jill Murphy. The series are primarily boarding school and fantasy stories, with eight books already published. The first one, The Worst Witch, was published in 1974 by Allison & Busby,[1] and the most recent one, First Prize for the Worst Witch, was published in 2018 by Puffin Books, the current publisher of all the series. The books have become some of the most successful titles on the Young Puffin paperback list and have sold more than 4 million copies.[2]
Miss Pentangle is the headmistress of Miss Pentangle's Academy for Witches, a fellow witch academy several mountaintops away from Cackle's Academy. In "The Worst Witch All at Sea", the unseen character Fenella Feverfew transfers there and leaves behind her regulation black cat since they have owls at Miss Pentangle's, although in The Worst Witch Saves The Day, Mildred reveals that the head girl there has a ragdoll cat, suggesting that the senior students can choose which animal they want. Mildred also describes Pentangle's Academy as being more up-to-date than Cackle's, and the students wear purple uniforms instead of black. In The Worst Witch Saves the Day, it is revealed that Miss Hardbroom is good friends with Miss Pentangle. 
In the first book of the series, it is revealed without explanation that Ethel and Mildred were enemies prior to the story. Ethel takes pleasure in taunting Mildred about her inability to train her cat into riding a broomstick, and Mildred responds by turning her into a pig. From then on Mildred and Ethel resent each other, and Ethel vows to get Mildred expelled. So far she has been unsuccessful. In the first five books she appears to have no friends, although her young sister, Sybil, makes an appearance in A Bad Spell for the Worst Witch. A friend of Ethel's, Drusilla, makes a brief appearance in The Worst Witch All at Sea and later plays a bigger part in The Worst Witch to the Rescue, where she hides Mildred's tortoise up a tree. Ethel is Mildred's arch-enemy.
In The Worst Witch Strikes Again she is assigned by Miss Cackle to show the new girl, Enid Nightshade, around the school, much to the chagrin and disappointment of both Maud and Miss Hardbroom. Throughout the novel, Enid gets Mildred into trouble without owning up. In A Bad Spell for the Worst Witch she is turned into a frog by Ethel Hallow after telling her younger sister a pretend story about Miss Hardbroom turning a pupil into a frog after being two seconds late for a lesson. This is how she discovers Algernon Rowan-Webb. In The Worst Witch All at Sea, after being given a normal black cat after Fenella Feverfew transferred to Miss Pentangle's Academy, Mildred disobeys orders and brings Tabby with her to Grim Cove. She also discovers a legendary treasure chest on Cat's Head Rock.
In Australia series 1–3 of "The Worst Witch" were released onto DVD as was "Weirdsister College", and both series of "The New Worst Witch" were released in 2007. Series one and two of "The Worst Witch" were released as one boxset, containing four discs which play on most DVD players (including the United Kingdom), as well as Series three and "Weirdsister College" on another boxset.
The Worst Witch to the Rescue (ISBN978-0-14-138301-9) was published in 2007 and features Ethel Hallow's only friend, Drusilla Paddock, in a largely increased role since her brief cameo in The Worst Witch All at Sea.
Maud Spellbody is Mildred's best friend. She is fiercely loyal to Mildred and assists her on most of her adventures, often against her better judgment. Maud is a decent and considerate person, but grows weary of Mildred's incessant clumsiness and often lectures her on how to improve herself. Ironically, Maud is not a perfect student, as she is also responsible for a laughing potion going wrong, as she along with Mildred had no idea how to make one. The Worst Witch All at Sea reveals her last name to be Spellbody, rather than "Moonshine", which is what the ITV series dubbed her.
"The Worst Witch" is a British ITV television series about a group of young witches at a Magic Academy.

Most episodes revolved around the school, following the adventures of Mildred and her friends. The series was later followed by "The New Worst Witch", which ran for two series and chronicled the experiences of Mildred's younger cousin Hettie as she attended the school. The series was rebooted in 2017 as "The Worst Witch", a co-production between CBBC, ZDF and Netflix.

The Worst Witch to the Rescue
In 2007, Shock released "Weirdsister College" on DVD, in a boxset with Series 3 of "The Worst Witch", although it is titled as "Series 4" of "The Worst Witch". Shock also released box sets of Series 1 & 2 of "The Worst Witch", and Series 1 & 2 of "The New Worst Witch". These are released only in Australia, but are playable worldwide.
In the later books Miss Hardbroom's humanity comes through on occasion, in incidents such as her accident in The Worst Witch All at Sea, the restoring of Mildred's hair to its rightful length in The Worst Witch Saves the Day, and her admitting of her error of judgment at the end of The Worst Witch to the Rescue.
Miss Constance Hardbroom is the terrifying and extremely strict form-mistress of Mildred, Maud, Enid, Ethel, and Drusilla. She is tall, thin and bony with waist-length black hair which she keeps ""scragged into such a tight knot that her forehead looked quite stretched"". Miss Hardbroom favours Ethel Hallow but has the complete opposite attitude to Mildred Hubble. Miss Hardbroom is even terrifying enough to reduce any pupil to a gibbering heap with one word. Despite seeming cruel, Miss Hardbroom's soft side does come through on occasions, such as her ""brief flicker of friendliness"" at the end of "The Worst Witch Saves the Day" and her admitting her error of judgement in "The Worst Witch to the Rescue" after it is revealed that Ethel stole Mildred's summer project for herself, Maud noting in "The Worst Witch and the Wishing Star" that Miss Hardbroom's dislike of cheats means that Ethel will be under close watch. 
The New Worst Witch is a British CITV television series about a group of young witches at a Witch Academy. It ran for 2 series from 2004–2007. The series was a spinoff from "The Worst Witch" which ran from 1998 to 2001.
The Worst Witch may also refer to:
Mildred "Millie" Hubble is the protagonist of the series. She is a good-hearted, but bungling young witch-in-training, who never seems to get anything right. She is friends with Maud Spellbody and Enid Nightshade and has a strong rivalry with Ethel Hallow. It is Miss Hardbroom, her potions teacher, who calls her "The Worst Witch".
Enid Nightshade is Mildred's second best friend who is introduced in "The Worst Witch Strikes Again" where she has hair "the colour of milky tea" wearing it in a thick plait and having large limbs. Mildred is assigned to look after her by Miss Cackle. Enid at first appears to be dull and boring but turns out to be a wild practical joker/prankster who is more likely to get the three into trouble than Mildred is. She unintentionally causes trouble for Mildred throughout the novel, even to the point where Miss Cackle threatens to expel Mildred if there is any more bother from her. Nevertheless, Enid is just as loyal as Maud is and provides comfort and support to Mildred in the following books of the series. Enid is the second worst witch in the Academy, as both she and Mildred are hapless at broomstick riding and lack the specific requirements to be fully-fledged, efficient witch. In the TV series, Enid was portrayed by Jessica Fox. In the new BBC reboot, Enid was portrayed by newcomer Tamara Smart.
Ethel Hallow is the snobbish, stuck-up, vindictive, and sly rival and enemy of Mildred and her friends. She is favoured by Miss Hardbroom, but appears to have no friends, apart from the rarely seen Drusilla Paddock, who is just as bad as Ethel. Ethel is described as being ""one of those lucky people for whom everything goes right"" which is what caused her to become so snobby. Ethel is tall and thin (just like Mildred) and has mousy-brown hair which she wears in a ponytail with a black hair ribbon. She also has a very spiky nose (pointed out by Maud in "A Bad Spell for the Worst Witch"). Various sources have noted that Ethel's primary weakness as a student is that, which she is able to easily follow the rules and perform new spells after demonstration, she lacks the ability to imagine and improvise when given free rein. This was demonstrated most clearly in "The Worst Witch to the Rescue", when she was the student who performed worst in the art class and had no ideas whatsoever for a summer project to research a spell of the student's choice as she lacked a framework for her to start studying in, in contrast to Mildred who not only performed best in art but had even created a completely new spell for the project.Because of her nasty ways, Ethel is sometimes seen as a bully. Yet her actions are instrumental in setting up the climax of nearly every novel.
In "The Worst Witch" the jinx she puts on the broomstick results in Mildred running away into the woods rather than face Miss Cackle. If Mildred hadn't run away she wouldn't have spotted Agatha Cackle and her coven.
In "The Worst Witch Strikes Again", if she hadn't locked Mildred and Enid in the store cupboard they would never have flown into the Great Hall to do a performance and improve Maud's speech.
In "A Bad Spell for the Worst Witch", if Ethel hadn't turned Mildred into a frog, Mildred wouldn't have discovered Algernon Rowan-Webb and he would have remained a frog for the rest of his life.
In "The Worst Witch All at Sea", if she hadn't set the boat adrift, the legendary treasure chest on Cat's Head Rock wouldn't have been discovered.
In "The Worst Witch Saves the Day", if Ethel hadn't left Tabby on the roof then Miss Granite wouldn't have picked him up and Mildred wouldn't have found out Miss Granite was actually Agatha Cackle in disguise.
While she is a straightforward bully in "The Worst Witch to the Rescue", where the main threat is Ethel stealing Mildred's summer project to pass off as her own, Ethel returns to her traditional role of unwittingly provoking success in "The Worst Witch and the Wishing Star", where her attempts to expose Mildred's new dog Star result in Mildred being granted permission to use Star as her broom companion rather than Tabby after she and Star win an inter-school competition.
The Worst Witch All at Sea (ISBN978-0-670-83253-8) was published in 1993. It is the only book in the series not set in Miss Cackle's Academy for Witches, but by the sea instead.
The Witches is a children's fantasy novel by the British writer Roald Dahl. The story is set partly in Norway and partly in the United Kingdom, and features the experiences of a young British boy and his Norwegian grandmother in a world where child-hating societies of witches secretly exist in every country. The witches are all ruled by the extremely vicious and powerful Grand High Witch, who in the story has just arrived in England to organise her worst plot ever. But an elderly former witch hunter and her young grandson find out about the evil plan and now they must do everything to stop it and defeat the witches.
The Worst Witch is a British-Canadian ITV television series about a group of young witches at a school for magic. The series stars Georgina Sherrington and Felicity Jones, and is based on "The Worst Witch" books by Jill Murphy (published from 1974 onwards). It aired for a total of 40 episodes spread over three series between 1998 and 2001, before being followed by "Weirdsister College." Most episodes revolved around the school, following the adventures of Mildred and her friends. The series was later followed by "The New Worst Witch", which ran for two series and chronicled the experiences of Mildred's younger cousin Hettie as she attended the school.
Many witches, especially in the Ramtops, have steadings; geographical areas and populations that they're responsible for. It is unclear how steadings are defined; Tiffany has the entire Chalk as a steading, while other witches have only two or three villages. Steadings are not necessarily passed on to the apprentice of the witch who previously watched over the steading. There does seem to be a particular geography to it; a discussion of the older witches dying off leads reluctantly to discussing a redrawing of territorial boundaries, which is getting more difficult to handle as there are fewer young girls becoming witches than there are older witches dying.
Drusilla Paddock is the older half-sister of Clarice crow and makes her first appearance in "The Worst Witch All at Sea". She claims a bed that Enid Nightshade offered to Mildred that looked like a hospital trolley. She has a much bigger role in the sixth book "The Worst Witch to the Rescue" where she hides Mildred's talking pet tortoise up a tree to prevent him from revealing the truth about Ethel's project. 
"Kasumi Ninja" received mixed to negative reception when it was released. While it received praise for its visuals, critics panned the controls, sound and slow gameplay, with many reviewers calling it a "Mortal Kombat" rip-off. By April 1, 1995, the game has sold more than 24,000 copies though it is unknown how many were sold in total during its lifetime and has since been called by some as one of the worst games of all time. A sequel, "Kasumi Ninja II", was in development for the Atari Jaguar CD but it was cancelled.
