Abuelita

 is a minor character in Gravity Falls.

History
Abuelita first appears in "Gideon Rises." After the events of the previous episode, "Dreamscaperers," Dipper, Mabel, and Stan are forced to move in with her due to Gideon's hostile takeover of the Mystery Shack. She is seen to be very tolerant of their presence, only asking that they keep relatively quiet. She cleans up any messes they happen to make with a vacuum, including Stan messing up her lipstick upon figuring out Gideon's secret and kissing her.

Personality
Abuelita is a very calm old woman, the years clearly having made her more apt to simply go with the flow. She has fairly simple wants and needs, desiring only quiet and cleanliness, as seen by her habit of instantly jumping to clean things the moment they're dirtied. Despite her somewhat sedentary behavior however, she's still quite aware of her surroundings, as she was quick to point out that she couldn't support the Pines' family for long with how much food she could afford. She speaks both English and Spanish.

Appearance
Abuelita is an elderly woman, with a somewhat portly frame and stout build, similar to her grandson. She has a head of tall, puffy, blue-grey hair, and wears a pair of pale emerald green earrings. While working around the house she typically wears a magenta shirt, and a 50's style cooking apron with a heart on it.

Trivia

 * Abuelita means "grandmother," or "granny," in Spanish.
