Donna Lou Who is the major character of the 2018 Illumination animated film, Dr. Seuss' The Grinch, based on the book How the Grinch Stole Christmas! by Dr. Seuss.
She's also the mother of Cindy Lou Who and twin infants sons, Buster and Bean, and she's voiced by Rashida Jones.
Every night, she worked overtime as the hospital nurse until morning and tried her best to catch the bus since she's so tired. At her house, she was making breakfast, trying to get something at the sink and overworked trying to take care of Cindy and her twin infant brothers, Bean and Buster.
She really love her children and do everything on her best to be happy especially on Christmas.
Before the Grinch steal Christmas, she was tucking Cindy into bed and told Cindy that whatever she ask Santa for Christmas, it must be really important to her (which it is since Cindy only wish to lighten her mother's workload since she always help others).
The next morning when The Grinch finally steal Christmas, the Whos wake up and are shocked to see that the presents and decorations are gone.
At first, Cindy believes that it was her fault, because she caught Santa, but Donna tells her that Christmas is more than just presents and that Cindy's the best thing that ever happened to her since she helps her mother out with her workload and the Whos join in singing.
The Grinch and Max soon hear the singing and the Grinch is puzzled to see that they're celebrating Christmas despite his theft, but he soon listens to their singing and his small heart triples in size.
The sleigh almost falls off Mount Crumpit and the Grinch tries to save it and soon. Fred and his family come to his aid. After securing the sleigh, the Grinch and Max go to Whoville to return the stolen items, admits his theft to the Whos and apologizes before going back to his cave.
Feeling sorry for the Grinch, Cindy comes to invite him to dinner at her house and he awkwardly attends. After he did, Donna was happy that he decided to come, welcome him, told him that he wear a nice tie and told Cindy that he came.
Later, Donna was having a hard time, holding the foods until the Grinch help her out and Donna was surprised at this by saying "Oh, that was so nice of him."
When seated down for dinner, Donna told the Grinch if he can carves the roast feast and the Grinch said "Um, sure. Is that okay if I say a few words?" Which Donna applies "Not at all".
Then, The Grinch admits that it wasn't really Christmas he disliked but being lonely and told Donna that Cindy was the first girl who show him some kindness and thank her daughter for that which Donna hug Cindy and smiles "That's my girl."
Then, the Grinch along with Max celebrates Christmas with the Whos and starts a new life with them, especially with Cindy and her family.
- She's based by Betty Lou Who and Martha May Whovier.
- It’s implied that her husband died after Buster and Bean were born or while she was pregnant with them.
- She's based by Betty Lou Who from the live action movie, because she does the housework, and she’s the widowed housewife. Also, she love her children so much and trying her best to be happy.
- She's based by Martha May Whovier, but differently like the appearance, hairstyle and Donna isn’t the love interest of The Grinch. The only thing that they're the same is they're both nice to The Grinch and look beautiful.
