Margaret

Margaret is a femal cardinal, (but she has a male cardinal's color scheme, females are brown) who works as a waitress at the coffee shop across the street from the park. She might be the only animal on the show who wears clothing. Mordecai has a major crush on her and is always finding ways to make excuses to go to the coffee shop she works at to see her.

Appearance
Margaret seems to have a very similar appearance to Mordecai. Instead, she is red rather than blue and she has a more curved beak. Unlike Mordecai, she doesn't have two white stripes on her arm, or black stripes on her fingers and her tail feathers. Her color scheme is unlike a regular red robin, where she is basically red.

Mordecai
Margaret cares for Mordecai and at times stands up for him (ex. In Caffeinated Concert Tickets when Slasher insulted Mordecai she told Slasher "Don't be such a jerk"). In Do Me A Solid, Mordecai made her laugh, however, minutes later, Mordecai spat in her face (from eating a super spicy burrito), and she seemed a little upset proclaiming "Its ok I don't even like this top". Later in the same episode when they went to the movies, Mordecai asked her for 5 bucks for popcorn and she seemed annoyed by this. Later they arrive at the house and Rigby tells Mordecai a very embarrassing soild that Mordecai denies to do. When chaos occurs, Margaret tells Mordecai that she does solids for Eileen all the time, and the only reason she went on the double date was because she was doing a solid for Eileen, So Eileen can be with Rigby. In this case, Margaret has no sign of love for Mordecai.But as seen in Mordecai and the Rigbys The future Mordecai refuses to admit whether or not he dates Margaret in the future.But margaret has lot of Boyfriends like Slasher and Angel (Mordecai and the Rigbys)
