Then wasn't seen until the half way point of the movie when she was hopping on her pogo-stick again, which attracted a Graboid to her that was stalking Walter's store. But Val and Nancy reached her before it could get her. Val sent Mindy inside with her mother and they climbed up to the roof. She was later seen on the house after Burt and Heather killed the Graboid, crying happily at the news. She later boarded the semi trailer with her mother to flee. Later, when everyone was forced to flee from it, Mindy fell down; however, Val picked her up and carried her to the rocks. When Val, Rhonda and Earl were stuck off the rock, Mindy helped make noise by yelling and whooping. After Stumpy was tricked into falling off a cliff, Mindy returned to living a normal life.
In the third film, however, she became an ambitious and attractive, twenty-year-old college student who had left Perfection for some time, but was forced to drop out of school and move back in with her mother when they couldn’t pay her school funds.
A while later, Burt warns them about Shriekers and tells them the government team were all killed. Her and Nancy hide in a box on the roof of Chang's Market when Burt tells them to hide the body heat.

Rosalita soon talks to her about Burt's house getting trashed, and she says that she doesn't know anything about. She soon goes to Ray, who is stuffing his pockets full of something, but he just claims that he doesn't know what happened and walks off.
She was going to leave her house, but her mother stopped her to ask her about what happened to Burt's place.
She can be seen walking away from the crowd, but her mother again stops her, and asks her what's going on.
