The New Worst Witch

Dyllis Mustardseed is an upbeat, though shy character in the series. At one point she uses a potion to increase her popularity.[1] She also enlists Hettie's help in all of the end-of-year projects. It is during the broomstick-flying test that she discovers the missing owl mascot from Pentangle's .[2] Within the second series she comes to her own as her character increases.

Dyllis with Hettie, Mona and Cressie

Dyllis also won the Golden Broomstick which was later stolen by Belladonna. She also helped when the academy was invaded by Agatha Cackle and Betty Bindweed by using her project that brought inanimate objects back to life when Agatha used it against the staff at Cackle's.[3]

Cackle's Academy is a thousand years old, and the highlight of the teachers' plans is a solo performance of the school song from Dyllis Mustardseed, who is terrified by the very thought. So Hettie, Mona and Cressie make her a transformation potion - a potion which will make bad people good, and shy people confident. To their amazement it actually works.[4]

Personality and Traits

Dyllis Mustardseed is an upbeat, though shy character. Dyllis once felt that she was so unpopular she stole the book "The Enchanted Book of Potions" from the library to make herself popular among her class mates except this caused the castle to go on lockdown and most activities were suspended and Henrietta Hubble was blamed for the stealing of the book, later Dyllis under a lying potion said she didn't take the book (since it was a lying potion, "no means yes"). Believing that Belladonna stole the book Hettie makes a truth potion but soon to everyone's amazement Dyllis admits that she took the book to make a popularity potion.[5]

Dyllis is a very unpopular student at Cackle's Academy; she spends most of her free time trying to find other girls from the school to be friends with. She takes a strong liking towards Cynthia Horrocks and Belladonna Bindweed, though she is also sort-of-friends with Henrietta Hubble.
