Molly adjusted her top hat outside the community hall, where balloons bobbed above the windows like colorful surveillance drones. Inside, a children’s party thundered with whistles, frosting, and an accordion playing tune. Bill crouched beside her, disguised as a birthday cake. His costume had cardboard layers, a candle helmet, and a cherry. Molly whispered, “Musical chairs: grab presents, escape through kitchen tonight.” Bill asked, “What if they make us play?” Molly replied, “We sit on the gift table.” They waited until the accordion player shouted for everyone to freeze. Molly entered carrying a clipboard labeled PARTY AUTHORITY. Bill waddled behind her, shedding sugar sprinkles. Bill bowed, accidentally head-butting a piñata. Candy exploded across the hallway, and a rubber chicken landed in his frosting. The children cheered. Molly seized the presents, discovering a wagon among them. She dragged the pile toward the kitchen while Bill distracted the crowd by pretending to be dessert. The birthday girl blocked their path, wearing a plastic crown and suspicion. Molly knelt, presented the clipboard, and announced an emergency frosting inspection. The girl considered this, then handed her a cupcake. The thieves fled, abandoning every present but stealing twelve cupcakes and the chicken.
