Molly spread the blueprint of the community center across the hood of their dented getaway van while Bill nervously juggled three stolen juice boxes. The target was not a bank vault but a seven-year-old's birthday party, stacked high with untouched presents. Bill whispered his concerns about security, which consisted of a single exhausted mother and a teenage magician. "Bill, wear the clown suit and cry loudly near balloons." Molly outlined the plan with surgical precision, involving a fake pony delivery and a smoke bomb made from birthday candles. Bill adjusted his ill-fitting animal suit and complained that his tail itched unbearably. "Perfect, I will sneak in and steal every wrapped present." Molly reminded him that the presents contained expensive gaming consoles and Lego sets worth a fortune on resale. They synchronized watches, checked the exit route past the bouncy castle, and prepared to infiltrate the chaos of screaming children and sugar-fueled mayhem awaiting inside. Their getaway driver was actually their nervous cousin dressed as a mascot who kept forgetting which building entrance led to the kitchen and which led to the bathroom, causing endless confusion before the heist even began. Molly sighed and checked her watch while children sang loudly.
