"While getting in as little trouble as possible."
To achieve that, they rely on their imagination, their determination, and... a fair amount of bad luck! For no mere mortal could survive the adventures of these three horsemen of the "apocadisp" and the crushing defeats they constantly endure! It can all start when they least expect it: in class, on a field trip to a museum, on a walk in the woods or a ride in the car, and then before they know it, everything is out of control.
