P came to the school to rescue her, but after some time, the Teacher turned infected.
Through unknown circumstances, the Teacher found Substance - 128 and supposedly drank it. It can be proven in the Piggy: Book 1 Credits and Book 2 Credits. Not much is known about the Teacher before the infection, but it's known that she taught education to students, like Zee and Zuzy, at the school. In a picture in Piggy: Book 1 credits, she has normal eyes and (by the looks of it) no ruler. She wears a purple dress and wields a yellow ruler as a weapon. Her eyes have black sclerae, small, yellow pupils and a cyan eye shadow. She is a tan gazelle with a large, brown nose, hot pink cheeks and pale grayish-red horns with tiny, triangular ears between them.
