!!Book 1: Lunch Walks Among Us
* Franny defeats the Pumpkin-Crab Monster after turning herself back into a little girl mad scientist by demanding the other children give her their lunches, using the meat from their sandwiches to construct a Lunch Meat Creature to fight the Pumpkin-Crab Monster, using the bread to create something soft to break Miss Shelly's fall when the Pumpkin-Crab Monster drops her and summoning some bats to hold the Pumpkin-Crab Monster in position as the Lunch Meat Creature uses the school's flagpole to knock the Pumpkin-Crab Monster away.

!!Book 3: The Invisible Fran
* Franny's quick thinking saves the day once again when she quickly thinks of ways to apply Erin, Lawrence and Phil's hobbies that defeat the two-headed robot.

!!Book 6: The Fran With Four Brains
* Franny using her ingenuity to outsmart the three Franbots and trick them into getting themselves destroyed, even if taking out the third one was more difficult due to not being as gullible as the other two.

!!Book 7: The Frandidate
* The titular shape-shifting suit Franny made to win the election for class president ends up hijacking Franny's attempt to persuade everyone to elect her President of the United States to instead persuade everyone on the planet to elect it King of the World. Igor saves the day by using Franny's [=ICU2=] (a machine that enables one to look at other people through their television sets) to show the face of Franny's mother. Sensing that what Mrs. Stein wants is the truth, the Frandidate has no choice but to reveal its true form and sheepishly admit to having no intention of keeping any of its promises. The suit had also been trying to suffocate Franny, with Franny's life being saved only by her creation being forced to come clean about its plans.

!!Book 9: Recipe for Disaster
* Franny is belittled by the two men who intended to carry away the school's old furnace, who even laugh at her when she boasts that she can make anything from the furnace. Franny's teacher Miss Shelly puts the two men in their place by revealing that Franny prevented a meteor from destroying the Earth last month by creating a rocket from an old refrigerator and a dollhouse, underscoring that the men have no right to talk down to Franny because they did not consider what she is capable of.
