Kida and Koda were bored. And when they were bored, things happened. Within minutes, half the posters and pictures on the walls of the classroom were upside down as well as every other book on the shelves nearest to them. They wondered when anyone would notice, but it wouldn't have been as fun if they had been caught in the middle of it. Sitting back in their seats, they looked around the room and started wondering what else could be done at this point. 
Koda looked back at his double. "Now that I think of it, where did those other students go? I thought we'd be seeing more here?" 
Kida shrugged. "If they're ditching, that's their problem. I just hope they stay away from the courtyard out front until we can see when the noise-crackers set off."
