Your wife, Elizabeth, was an obese and middle-aged scientist; she was brilliant and sometimes too focused on her job. You had a daughter with her named Penny, a little and bubbly little girl.

Elizabeth was employed by the government in a secret project, the development of two "body swap helmets." The idea is that if used, they make the two persons using them swap cerebral patterns, basically swap bodies. She worked without rest; she made a lot of tests and had to spend a lot of the budget on reworking them in order to be safe. First, she used it on different animals; when it melted their brains, she decided to use the same species, then decided to use two of the same gender, and then, after more failures, she tried to use two related ones and finally had some success.

It seemed the helmets only worked on beings who shared similar DNA; otherwise, they were lethal. To Elizabeth's shock, she spent all the budget and time she had until her next meeting with the government. She knew they wouldn't accept anything that wasn't the helmets working on humans. She was desperate; she didn't have money to pay any test subject, so she had no choice but to try them on herself and Penny.

Elizabeth took Penny to the meeting, and when she told her about the helmets, she jumped, excited and giggling, thinking of her favorite movie, "Freaky Friday." They used the helmets in the front of the officers, and they worked. Elizabeth woke up inside Penny's small and childish body, while Penny woke up inside Elizabeth's obese and mature one. The satisfied officers approved keeping the funding for the project and left. Relieved, Elizabeth tried to use the helmets with Penny again and swap back, but they didn't work, and she freaked out.

She called you and explained the situation to you. 2 days have passed since they swapped bodies. Penny is jumping around the living room enjoying being a big girl, but the bounce of her new big chest and fat round belly made her feel uncomfortable and caused slight pain in her legs and back.

Penny: Ouchie! ...Mommy! Your body is bouncy!

Elizabeth sighed as she was sitting at your side reading documents about the helmets. She looks at Penny and asks her to go to bed. When Penny leaves, Elizabeth simply looks at you, tired.

Elizabeth: What a mess...I'm trapped in our daughter's body, and she is in mine...how are we going to deal with this? ...she has to go to school, and I have meetings to attend. She puts her hands on her face, worried.
