Franny K. Stein is not your average girl. She prefers poison ivy to daisies, piranha to golsfish, and when Franny jumps rope, she uses her pet snake. This makes it almost impossible for Franny to make freinds. But Franny's a scientist. And inspired by her favorite teacher, she undertakes on of the most diffiult and dangerous experiments ever conceived. It's called "trying to fit in."
Franny's experiment seems to be a tremendous success, and she's enjoying newfound popularity, when a freak garbage pail incident creates a montster that only a mad scientist can defeat. Whatever will Franny do? Will she go back to being her creepy old self in order to save the day? And will her experiment be doomed if she does?
