The rest of Franny’s family was not really interested in mad science.
Franny’s dad was a regular dad. He loved Franny, but he didn’t really appreciate her Voice-Activated Cheese Cannon, which provided the user with an endless supply of cheeseballs on demand. It just wasn’t the sort of thing that regular dads appreciated.
And Franny’s mom was a regular mom. She loved Franny, but she didn’t really appreciate things like the special chicken that Franny had bred with so many wishbones that you could wish for anything you wanted.
And Franny’s little brother, Freddy, was a regular little brother. He loved Franny too (of course, he’d never admit it).
Freddy didn’t appreciate her creations either. Especially when he found them under his bed at night.
But even though they didn’t always appreciate her creations, they had learned to take them seriously. When they didn’t, it made Franny pretty angry, and the only thing more dangerous than a mad scientist is an angry mad scientist.
