Molly and Bill huddled in their dimly lit van parked across from the suburban McMansion, binoculars trained on the backyard where balloons bobbed and squealing kids swarmed a mountain of gift-wrapped loot. Blueprints of the house lay spread across the dashboard, annotated with crayon scribbles. "Bill, it's perfect," Molly whispered, eyes gleaming. "We crash as the 'Magic Unicorn Entertainers.' I got the costumes—hooves and all." Bill snorted, adjusting his fake mustache. "Hooves? How we gonna run with sacks of Barbies and Xboxen? Nah, we spike the punch with sleepy-time juice. Kids conk out, parents tipsy, we grab and dash." Molly slapped his arm. "Genius! But what about that bouncy castle? It's a fortress of snot-nosed guards." "Piñata ploy!" Bill cackled. "I swing the stick, you rig it with candy explosives. Boom—distraction city. Presents ours in sixty seconds flat." "Explosives? You're nuts," Molly laughed. "Fine, but if Clowny Carl shows, you're decoy. Last time you juggled, we almost got pinched." Bill winked. "Deal. At 3 PM sharp, Operation Present Heist launches. Richest score since that Easter Bunny gig." As laughter echoed, a kid spotted the van and waved. Molly floored it, hearts pounding with glee.
