Miss Agatha Trunchbull (nicknamed The Trunchbull) is the fictional headmistress of Crunchem Hall Primary School (or Elementary School) and the main antagonist in Roald Dahl's 1988 novel Matilda and its adaptations: the 1996 film Matilda (in which she was played by Pam Ferris), the 2011 musical, and the 2022 musical film adaptation (in which she was played by Emma Thompson). She is said to look "more like a rather eccentric and bloodthirsty follower of the stag hounds than the headmistress of a nice school for children"
Friendship has been replaced by fear in Equestria. Sunny, an Earth pony, and Izzy, a unicorn, embark on an adventure that takes them to faraway lands and challenges them to make new friends as they strive to restore harmony to Equestria.
