She first appears in "Headhunters" attending Stan Pines' unveiling of his new wax figure and the grand re-opening of the Gravity Falls wax museum, and was the one who pointed out that he had promised everybody free pizza if they came, to which he replies that it was "a typo."
Later, it is revealed that Toby Determined, head of the failing Gravity Falls Gossiper, has a crush on her. He keeps a cardboard cutout of her in his closet, which he made out with once when he was alone. 'Lil Gideon gave Toby Shandra's phone number as part of a deal to get back at Dipper Pines in "The Hand That Rocks the Mabel."
In "Gideon Rises", she does a report on the Mystery Shack, which is under Gideon's control, and Gideon's arrest.
She is a tall, tan woman with reddish-brown hair. She wears a light blue shirt with a slightly darker blue vest and a black skirt that goes down to her knees. She has visible cheek bones, a mole on her face, and wears dark pink lipstick. She usually carries a microphone.
- Her name could be based on Sean Jimenez, Gravity Falls' Background Design Supervisor, who also attended the California Institute of Arts School of Film/Video like creator Alex Hirsch, or on Sarah Jimenez, one of Alex Hirsch's friends from when he attended CalArts.
