Sally Snuffleupagus, often referred to as just Mommy Snuffleupagus, is a loving Snuffleupagus matriarch on Sesame Street. She is given her name in Episode 1821.
She makes her profession as a banker, working for the Snuffleupagus Bank & Trust. In Episode 2099, she has to travel to Carlsbad (famous for its caverns), so she recruits Gordon to babysit for Snuffy.
Mommy Snuffle plays a role similar to that of Big Bird's Granny Bird. She appears only on a sporadic basis and exists primarily in books or as a kindly off-screen presence, mentioned but not seen very often.
In the unaired divorce episode, Noel MacNeal remained the puppeteer, but Lynn Hippen was hired as the voice because the producers felt they needed a female voice for the character.[1]
A telephone fastened to a tree magically appears in front of Big Bird and Snuffy out in the plains of the Hawaiian islands. Snuffy takes a long-distance call from his mommy.
Snuffy's mommy answers the door when Big Bird visits the cave for the first time (and is surprised to meet Big Bird, having thought he was Snuffy's imaginary friend), and later calls the two over to have dinner.
After purchasing a hat Snuffy claims to have needed to get for his mommy, she then arrives and Big Bird presents it to her, though she has no idea what they're talking about.
