She first appeared in "Headhunters," attending Stan Pines' unveiling of his new wax figure at the grand re-opening of the Wax Museum of Mystery. While there, she said that Toby Determined, head of the failing Gravity Falls Gossiper, is not a real reporter while stating that she is, and pointed out that Stan had promised everybody a free pizza if they came, to which Stan replied that it was "a typo." Later, it is revealed that Toby has a crush on her. He keeps a life-sized cardboard cutout of her in his closet, which he made out with at least once when he was alone.
In "Society of the Blind Eye," she is mentioned in the end page's cryptogram.
In "The Stanchurian Candidate," she reports the death of Mayor Befufftlefumpter. She breaks down in tears during the report, not because she finds it sad, but because it is the first piece of real news she's reported on in some time. After the mayoral debate, she reports that Stan was disqualified due to his numerous crimes, and that Tyler Cutebiker is now the new mayor of Gravity Falls, Oregon.
She is a tall, tan woman with brown hair. She wears a light blue shirt with a slightly darker blue-gray vest and a black skirt that goes down to her knees. She has high, distinct cheekbones, a "beauty mark" mole on her face, and wears dark pink lipstick.
