g days of the year for students. Imaginations--and children--run amok, fueled by thoughts of pumpkins, trick-or-treat plans, and sugar highs. But at school, their teachers dread the yearly shenanigans, and this year, the students have started celebrating a day early. With princesses running a tiara trade ring in the girls' bathroom and a laser sword battle among fourth-grade space rangers, the kids are quickly taking control of the school! When a group of fifth-grade monsters tie up two first-graders and prepare to eat them, the teachers are ready to call it quits! It's up to the students and their parents to show the teachers a new kind of Halloween and give them a holiday treat they'll never forget.
