The Fall Family Fitness Festival promises to be the highlight of Justice Payne Middle School's year—as long as the sixth graders can overcome their nerves long enough to present their physical activity to the public. But two hours before the festival's start, students arrive at the gym to a disaster: Hailey's yoga station and Dawson's karate station have been trashed. Who would have ruined these stations? Was it a rival karate kid? Or maybe it was Dawson himself, hoping to prevent a recap of his previous disastrous brick-breaking attempt? Was it the new girl trying to take Hailey's spot in her friend group? Or was it a concerned father, hoping to get his daughter out of the project? Crack open a What Happened? book to investigate a preposterous mystery from four different perspectives. See what the witnesses gets right . . . and what they get hilariously wrong. Bet you'll never guess what really happened!
