Cookie Monster’s Grandma is Cookie Monster's grandmother, appearing prominently in the 2006 DVD series, Sesame Beginnings. She had previously appeared in a Sesame Street News sketch in 1979 as Little Red Riding Hood's granny, performed by Cheryl Blaylock. Cookie's grandma also made an appearance in a Monsterpiece Theater story, Little Red Riding Cookie, performed by David Rudman. These could be different grandmothers than the one who appears in Sesame Beginnings.
