Mildred is a small rectangular milk carton that is completely white and open at the top, empty of contents. There is a blue face on one side, presumably drawn on in a lopsided way.
Mildred first appears in "Missing Milo", after Scott leads Melissa and Zack out of the sewers. Once they're gone, he promptly turns and scolds Mildred for expecting him to introduce everyone who comes down to the sewers.
In "Teacher Feature", Mildred is separated from Scott when a garbage man collects her alongside the trash. She returns to him at the end of the episode, where she catches Scott bringing in an orange juice carton named 'Cynthia', much to his horror.
In "Adventure Buddies", she takes all of Scott's time, making Doofenshmirtz frustrated. Later when Doof tries to mimic the relationship Scott has with her, she sends him to a bathtub suspended over the sewer water. When the ship is going over a waterfall and she falls out, Doof saves her. When they are all drying off, she asks Doof to stay with her and Scott. Doof declines and goes back to the Murphy's.
In "Safety First", she attends a therapy session with Scott.
