Two heads...Are dumber than one.

Goosebumps and Bill Nye the Science Guy fans, meet Franny! There’s nothing better than being a mad scientist—at least according to Franny. So she’s making it her mission to help her classmates discover their own inner mad scientists. All Franny needs for her latest experiment is a few volunteers, a half-completed two-headed robot, and an invisibility potion. Only this experiment just might prove to be Franny’s most difficult. Because what do you do when your classmates don’t know anything about mad science—and there’s a doubly dumb robot running amok to prove it?

It's time...for a change!

Franny's faithful lab assistant, Igor, has swallowed a doomsday device that is ready to go off at any moment! For any regular scientist, there is only one way to get the device out -- um...make that two ways. But Franny K. Stein is no ordinary scientist, so she concocts her own way to get the device back and save her friend. With her miniaturization machine, Franny shrinks herself to the size of a pin and goes on a field trip like no other...through the body of a ticking time-dog! Fasten your seatbelts, it's going to be a bumpy ride!

Franny K. Stein is not your average girl—she’s a mad scientist. She prefers poison ivy to daisies, and when Franny jumps rope, she uses her pet snake. The kids in Franny’s class think she’s weird, wacky, and just plain creepy. Tired of being stared at, Franny decides to attempt her most dangerous experiment yet—she’s going to fit in. But when a giant Monstrous Fiend attacks the class, everyone knows only a true mad scientist can save the day. But has Franny lost her creepy, crawly ways?
