Trixie
Trixie is a character originated by Patricia Quinn in the original 1973 London Cast Royal Court Theatre production of The Rocky Horror Show, originally produced in the theatre's second space known as "The Theatre Upstairs". The script is vague in regards to this character, referring to her as Magenta (as Usherette). The tray she carried as the Usherette contains a prop with the words "Strawberry Time", which the cast then expanded to call her "Miss Strawberry Time", however the character is not referred to, as such, in the musical. It was not until the show opened in the US in 1974 at the Roxy Theatre that she was first known as Trixie, having the name written across the front of the tray.
Trixie is a personification of the The Lips singing "Science Fiction, Double Feature" during the opening credits of The Rocky Horror Picture Show and her performance is open to interpretation.
