Elmo's grandparents

Elmo's grandparents, known simply to Elmo as "Grandpa" and "Grandma," have appeared in illustrated storybooks and in a 2014 episode of Sesame Street.

They live on a farm and Elmo and his sister Daisy visited them in the 1990 Sesame Street book Elmo Gets Homesick. The couple returned the favor 18 years later, visiting Sesame Street in the 2008 book What's the Word on the Street?

In 2014, Elmo's grandparents made their first on-screen appearance as Muppets. In episode 4417, Elmo's Grandpa and Grandma participated in a video-chat with Elmo and his friends on Sesame Street. In this appearance, Elmo's Grandpa and Grandma were performed by Tyler Bunch and Stephanie D'Abruzzo.

It is never stated if these are Elmo's paternal or maternal grandparents, hoever Elmo's Grandpa bears a strong resemblance to Louie, Elmo's dad, and their red fur imply that they could be Elmo's paternal grandparent (as opposed to being the parents of Elmo's mother). This would make them the parents of both Louie and his brother Jack; and thus the grandparents of both Elmo and Daisy, and their cousin Jesse.
