Granny Grouch
From Muppet Wiki
Granny Grouch, Oscar's grandmother, appeared in Sesame Street's Season 2's premiere, Episode 0131. She knows that her grandchildren hate her big wet kisses, so she kisses them as often as she can. Whether Granny Grouch is Oscar's maternal or paternal grandmother or wed to Grandpa Grouch is unknown.
The puppet is an altered version of the very first green Oscar, as he appeared on episode #5 of The Flip Wilson Show in 1970.
