This year´s fifth graders are the worst principal klein has ever seen.
But he´s hoping that Spirit Week can teach teamwork, with a secret prize for the winning team as incentive.
Best friends George and Lilly have been looking forward to Spirit Week all year. They might be complete opposites, but together they know they´ll be undefeatable. When they end up rivals, with Lilly leading Team Red and George leading Team Blue, the two swear they can complete and reamin best friends.
But the week starts with Lilly ruining Twin Day for Team Blue, and war is quickly declared among the entire grade. Suddenly, there are slimed lockers, sabotaged costumes, and class pets held hostage. As the pranks escalate, they threaten everything, including the prize. Because if principal Klein finds out, Spirit Week will be canceled and the fifth grade will end up in detention forever. Or worse.
Can george and Lilly find a way to fix their friendship and get everyone to play fair... or is the most awesome week of fifth grade about to make this the worst school year ever?
