As a little girl, Rosy is consistently kind and sweet, having a close friendship with Jenna. In the beginning, she is shown as the only human who genuinely likes Balto and tries to befriend him. This carries over to her as a woman old enough to be a grandmother, as she remembers Balto fondly for having saved her life by bringing the medicine. And she is also known as respectful, optimistic, selfless, intelligent, energetic, relaxed, outgoing, social, imaginative and even-tempered.
Rosy first appears as a little girl excited over receiving her first sled from her parents and the carpenter who made it for her. With a new musher's hat as well, she immediately harnesses her dog, Jenna, to the sled. They head off to the dog-sled race, Rosy still full of enthusiasm.
At the dog-sled race, she temporarily lets Jenna loose before eventually looking for her and hugging her while they watch the dogs coming in. She starts cheering for Steele's team until her hat is blown away by the wind into the racing track. She tries to get it, but Jenna grabs hold of her jacket to avoid letting her be possibly run over in the race. Balto intervenes to jump into the race and retrieve the hat for her.
Rosy is grateful to Balto, mock-admonishing him for doing such a crazy thing just to impress a pretty girl. She then tries to harness Balto to her sled as well so he and Jenna can be a team together, but her father stops her and pulls her away to scold her about how Balto is part-wolf and will bite her. She protests, telling him he hurt Balto's feelings, as Balto leaves and she has to head home with her parents and Jenna.
Later, Rosy ends up in the hospital with numerous other children. When she sees Jenna waiting outside through the window, she runs out to play with her before her father catches her outside and brings her back in. Once back inside, the doctor checks her vital signs and puts her to bed, telling her to get plenty of rest while leaving to tell her parents that she, like many other children in the town, has caught diphtheria.
While she lays ill in bed, Jenna keeps watch over her outside the hospital window. Eventually, her parents and the doctor allow Jenna to go in and visit her as a form of treatment. Jenna comforts her by laying her head next to her while she falls asleep again. Balto, watching outside the window, is further motivated by this in his decision to find the sled team to bring back the medicine.
Near the end, she is still lying in bed when Balto and the team arrive with the medicine. She receives it along with the other ill children and becomes recovered enough to sit up. When she sees Balto, she hugs him and thanks him, telling him, "Thank you, Balto. I would've been lost without you."
At the very end, Rosy finishes telling the story and she and her granddaughter continue the search until they find Balto's statue. At the statue, while her granddaughter plays with her dog, the now-aged Rosy looks up at the statue and repeats what she said as a little girl, revealing to the audience that she is the same Rosy from the story.
Rosy is mentioned several times that she's going in a picnic, but she remains off-screen.
Rosy has a cameo during the opening credits as she would be seen sleeping then it shows her spending time with Balto and Jenna.
- She is the only human who technically appears in all three films.
- Her design was also inspired by Audrey Hepburn, along with Jenna.
- There was a deleted scene where she would come in Balto's defense along with Jenna after her dad was shoeing away with a broom out of his store.
