Molly unrolled the sticky blueprints across the metal hood of their van. A smeared purple juice box ring marked the exact location of the target. She tapped a freshly manicured fingernail against the paper diagram of the suburban backyard. It was a complete tactical nightmare. "The clown arrives exactly at noon." There were five heavily sugared children roaming the perimeter, armed with water balloons and an absolute disregard for human decency. Bill adjusted his dark ski mask, wiping a bead of nervous sweat from his forehead. He had successfully robbed casinos, art galleries, and a diamond syndicate, but a petting zoo birthday party was an entirely different beast. A miniature pony was already eyeing him with suspicion from across the immaculate lawn. The glittering mountain of wrapped presents sat vulnerable beneath a pink gazebo, begging to be liberated by trained professionals. They needed absolute precision. "I will bypass the bouncy castle." "Do not touch the piƱata." Bill sighed heavily. "I need sugar." Molly checked her tactical stopwatch, synchronized to the rotation of the cotton candy machine. They were ready to infiltrate the property, neutralize the highly energetic toddlers with distraction maneuvers, and quietly escape with every brightly colored gift box.
