Your ultimate goal for the fourth grade is simple: you must be the greatest scientist to ever walk the halls. You are well on your way when your rival scientist friend begs you to help her earn a scout badge by cultivating the exact mold that produces penicillin. Being a brilliant expert on all things gross and slimy, you are thrilled to tackle the challenge. But your focus gets completely derailed when your best friend decides to run for class president and demands that you serve as his top campaign manager. If juggling politics and penicillin is not hard enough, you are suddenly stuck with a bizarre new babysitter who acts suspiciously like a teenage alien from the Planet Pink. When she accidentally throws away your prized dried worm collection, your scientific timeline is thrown into total chaos. You will have to use serious problem-solving skills to win the election, survive the alien babysitter, and master the mold.
