Mommy Snuffle plays a role similar to that of Big Bird'sGranny Bird. She appears only on a sporadic basis and exists primarily in books or as a kindly off-screen presence, mentioned but not seen.
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.
