In Toy Story 3, Molly is first seen as a toddler during the old home videos Ms. Davis took when Andy was young. Many years later, she appears as a 12-year-old. She is first seen in Andy's room laughing on why Andy still has his old toys but is lectured by Andy and their mother. She then donates a whole bunch of things including Barbie, and listens to music while reading a Tween magazine. She is last seen at the end of the film, she is seen asking if Andy is going to say goodbye to Buster.

Toy Story 4
Relationship with Andy
- Andy: "So, you gonna miss me when I’m gone?"
- Molly: "If I say no, do I still get your room?"
- Andy: "Nope."
- Molly: "Then, yes, I’ll miss you."
- ―Andy and Molly as he helps her carry her box downstairs[src]
In the first film, Andy shares his room with Molly and doesn't seem to have a problem with it. In the second film, they have separate rooms, but as seen in the clips at the start of the third film, Andy still doesn't mind Molly being in his room. He is seen at the end of the second film helping his sister walk to their mother and comments that he can teach her to drive. However, by the present time in the third film, Andy, having developed a more teenager-like personality, is much less willing to let Molly be in his room and doesn't allow her to touch his things, but still loves her. He helps her with a box full of toys she chose to donate to Sunnyside, and asks her if she will miss him. She then asks her brother if she can still have his room if she says "no", believing it will be hers when he leaves. When Andy says "nope", Molly replies that she will miss him. Near the end of the film, Andy mentions that he and Molly "said goodbye like 10 times", suggesting they are close.
- Although Mrs. Potato Head and Bo Peep are her toys, they seem to be Andy's as we always see him playing with them.
- Because of Molly's tendency to drool on any toys she could get her hands on as a baby as seen in Toy Story, she earned the nickname "Princess Drool" from the toys, especially Mr. Potato Head.
- In a part of Toy Story 3 when Molly is playing outside the house, it is shown that she might enjoy playing with Buster as well.
- Darla from Finding Nemo makes an appearance in Toy Story 3 on Molly Davis' magazine.
- Someone was holding the model of Molly at the airport in Toy Story 2.
