The Worst Witch
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".
The Worst Witch
There, Mildred meets another frog who also was a human once called Algernon Rowan-Webb. Algernon reveals that he was turned into a frog by a fellow magician after an argument. Algernon also reveals that the one thing he craves is some toast and crumpets with butter.
