Elmo's Grandma
From Muppet Wiki
Elmo's Grandma has two grandchildren, Elmo and Daisy. She lives on a farm with Elmo's Grandpa. She likes to bake marshmallow cookies and apple pie. Elmo visits her in the 1990 book Elmo Gets Homesick.
She returns the favor 18 years later, visiting Sesame Street in the 2008 book What's the Word on the Street?
