Cora

Cora is a cousin of Arthur, D.W. and Baby Kate.

Biography
In "D.W. Thinks Big", Cora arrives for a sleepover at the Read household to prepare for the wedding of her aunt Lucy the next day. In D.W.'s room, D.W. asks Cora if she wants to play with her doll, Madame Curie, but Cora is unimpressed by it, calling it "baby stuff" and says she doesn't have time to play anyway as she has to prepare for the wedding since she is the flower girl. While checking her supplies, Cora shows D.W. a golden heart-shaped locket that Lucy gave her as a reward for being the flower girl. D.W. tries to touch it, but Cora tells her she can't because it is made out of real gold, and then intentionally breaks the locket by pulling on it and acts like it was D.W.'s fault for making her do it. She then goes to tell her mother that D.W. was the one who broke it, and Jessica scolds D.W. for it. She tries to claim she didn't do it, but Cora argues back saying that she did and ruined it. Cora and D.W. are then sent to bed by Jane, and Cora asks Jessica if she could sleep with her because she thinks the colors in D.W.'s room are awful, but Jessica tells her she is just tired.

The next day, Cora is given her flower crown for the wedding and her father takes a picture of her in her wedding outfit. At the wedding, she rudely reminds Arthur that if he makes a mistake, he'll ruin the wedding. While Arthur and Cora are walking down the aisle (Arthur is the ring bearer), Cora rudely yells at him to smile, which startles him and causes him to lose his balance, and as a result, the ring flies into the air and lands inside one of the organ pipes. Grandpa Dave tries to pull it out but is unsuccessful. The organ player, an elderly female rabbit, then points out that if someone could fit into the small hatch on the side of the organ, they could go and retrieve the ring. Arthur tries it out but it turns out he is too big to fit. Dave then asks Cora to give it a shot, which she is about to do, but then backs down when she sees that the inside of the organ is dirty, and rudely asks if they can just get another ring instead, to which Jessica answers affirmatively and tells her that she doesn't have to go into the organ. The wedding attendees then go into a panic, until D.W. volunteers to go retrieve the ring. While D.W. is inside the organ, Cora is seen watching in astonishment along with David, Jane, Arthur, Dave, and the organ player. After D.W. gets the ring back, Cora is stripped of her flower girl position by Lucy and it is given to D.W. instead, which Cora isn't happy about, but Lucy scolds her for opposing it, and she begrudgingly says it's alright.

Cora is last seen near the end of the episode among the crowd waving outside Lucy and her husband's wedding car.

In Brain's dream where he was a bug, Cora was seen at Lakewood talking to Nancy.

When Grandma Thora was shopping for her birthday, she decided to buy Arthur the Mutant Muck Monster as a present.

Personality
Though she only appears once in the series, Cora is portrayed as being spoiled, annoying and rather rude to the Read family children, especially D.W., but acts like a little angel when the adults are around. She acted nice only once to D.W. when she asked her on the night before the wedding, where she was going to sleep. Her bratty nature is later exposed at her aunt Lucy's wedding.

Physical appearance
Cora is an aardvark with a light brown complexion. She wears a blue short-sleeved dress with green stripes at the bottom and on her sleeves, long white socks, and red-and-white sneakers just like Arthur's sneakers. She has short brown curly hair. She wore a lavender dress with puffy sleeves, beige pantyhose and white shoes to the wedding since she was the flower girl.
