Phineas and Ferb episode "The Fast and The Phineas"
Vivian Garcia-Shapiro is the mother of Isabella Garcia-Shapiro and lives across the street from Phineas and Ferb. She plays in a Freelance Jazz band with Linda Flynn and Mrs. Johnson, where she play contrabass. She is known to talk very fast causing distractions with useless comments. She is known to be Mexican and Jewish. She comments a lot on how tall Candace has gotten. Vivian has long black hair tied with a green ribbon. She wears a white shirt under an orange jacket. She has golden hoop earrings. Maroon pants and brown sandals complete her look. Her physique is round and short; she is slightly shorter than Linda Flynn-Fletcher.
Vivian seems to embody both of her last names: She appears to be Hispanic, yet speaks with a Yiddish accent.
She revealed that she is a descendant Mexican-Jewish culture ("Picture This").
Vivian reveals that Candace, at some point in her life, was wearing braces ("The Fast and the Phineas"). She also thinks Candace is too thin, and encourages her to eat by offering her a matzah-ballrrito (a portmanteau of "matzah-ball" and "burrito") ("Picture This"). She may enjoy the burritos herself, which is a marriage of staple foods in both the Mexican and Jewish cultures.
Vivian calls her daughter "Isa", which is a common shortening of her name in Spanish-speaking countries ("Hide and Seek").
Vivian is shown to most likely be married since she has a wedding ring, although she is never seen wearing it ("No More Bunny Business").
