The Fran That Time Forgot

The Fran That Time Forgot is the fourth book in the Franny K. Stein book series.

Plot
Franny wins the school science fair by inventing a Time Warp Dessert Plate to disprove the old saying that you can't have your cake and eat it, too. When her certificate is handed over, Franny is then humiliated when everyone laughs at the revelation that her middle name is Kissypie, a nickname her father gave to her mother when they were dating that became Franny's middle name because they thought it would be cute to give it to her.

As she gets angry at everyone laughing at her middle name, it occurs to Franny that she can go back in time and change her middle name, so she gets to work on retooling her Time Warp Dessert Plate to work on herself while ignoring her mother's demands that she clean her room.

Franny goes back in time to the day she was born and meets herself as a baby, asking her for suggestions on what her new middle name should be. Baby Franny turns down every name beginning with K that her future self suggests, but ends up inspiring her when she takes out her pacifier and exclaims "Kaboom". Pleased by the suggestion, Franny goes ahead with changing her middle name to Kaboom and leaves, but not before telling Baby Franny that there is nothing worse than being laughed at and drawing extra eyes on the elephant doll in Baby Franny's bassinet, which is implied to spark Franny's interest in mad science.

Before returning to the present, Franny gets curious at how she'll be when she's older, so she decides to visit the future. Franny finds her house dilapidated and swarming with all sorts of grotesque creatures. As she enters her house, she sees no sign of Igor, her parents or her brother and finds that her teenage self has been toiling away for years to get back at everyone laughing at her middle name.

Realizing that it wasn't her middle name that needed to change but how she reacted to people laughing at it, Franny tries to stop Teen Franny's plan of creating an army of elephant monsters, but finds that she and her future self are evenly matched. Franny then gets the idea to go back to the day everyone laughed at her middle name and ultimately prevents the dismal future from happening by agreeing with her peers that her middle name is funny and letting herself join the fun in laughing at it.

Franny then proceeds to clean up her room like her mother asked, with Igor's help.
