Nana Noodleman is an anthropomorphic black Suffolk sheep. She wears a purple dress and purple transparent sleeves and purple head bands with a purple gem and pink feathers. She has a purple feather fan. She also has a pink necklace. She wears gold earrings as well as three gold bracelets on her arms.
In Sing 2, she has similar accessories and clothing, except it is mostly green instead of purple.
A grand old dame of the theater, Nana Noodleman fondly remembers her glory days as a theater actress, holding the theater where she used to perform sacred, a place of wonder and magic.
However, she has a snobbish and irritable side to her. Although, this might be because of her old age. Even her grandson, Eddie, considers her to be "one mean sheep".
Nana originally has a clear dislike of Buster Moon, considering him a charlatan who has failed to make the theater as beloved as it was back in her day, and even refuses to help him in any way shape or form since she knows that he doesn't have the money. However, she accepts to view a private screening of his singing competition, albeit as she claims she has nothing better to do other than to play checkers with her butler, Hobbs. She entertains the idea of providing the prize money if she is impressed, only to ultimately witness the bears' interruption and the theater's literal downfall and leaves while giving Buster a piercing look of fury.
Despite her stubbornness and snooty demeanor however, Nana attends the show Buster and his singers put together and after a successful performance by all of them, Nana not only joins in the applause but gives a congratulatory smile to Buster from the audience, despite having to pull a quill from Ash from her hair.
Nana became a kind and thoughtful person when she buys the theater property and restores it, attending the grand re-opening with Eddie, and has clearly come to respect Buster and appreciate his own love for theater is equal to, if not greater than, her own.
Since then, Nana has regularly attended shows, musicals, and performances produced by Buster at the New Moon Theater, and they have apparently become good friends and even confidantes, as Nana seems to have taken on a sort of mentor-esque role for Buster, encouraging him to follow his dreams and to take the bad along with the good. She takes pride in Buster's accomplishments and was awed by his musical, Out of This World, being performed in the Majestic Palace Theater, whereupon she blew a kiss to the performers, her way of wishing them luck.
Nana Noodleman is the considerably wealthy grandmother of Eddie, and a retired theater actress and singer, having performed at the same theater Buster Moon grew up to own and run, and she is partly the reason Buster fell in love with theater.
Nana Noodleman is Eddie's maternal grandmother, through her daughter.
Her husband is never seen or mentioned; therefore it is likely that they are either divorced or he is deceased.
In separate scenes, Buster and Mike were both surprised to hear that Nana is still alive.
One of her most famous performances in the musical "Epiphany" is shown in the very beginning of the movie. She is seen singing "Golden Slumbers". This is what led the then-6-year-old Buster Moon to have a passion for theater.
