Mrs. Tibble

Mrs. Tibble is the grandmother of Timmy and Tommy Tibble and the mother of Trixie. She takes care of the twins for her daughter, who travels around the world. In Desperately Seeking Stanley, Arthur Read discovers that she is a toy maker and has repaired a large collection of antique toys.

Appearance
Mrs. Tibble is depicted as a bear with a brown complexion, gray hair worn in a bun, and wears a bluish-green dress, a white shirt, a pink button-up shirt, and pink high-heeled shoes. When she first appeared in the book Arthur's Halloween that was first published in 1982, and returned in the 1992 book Arthur Babysits, she and the Tibble Twins were humans although they later became bears for the cartoon, but they're still humans in the later books.
