Molly spread the birthday invitation across their wobbly kitchen table. “The party starts at three. We strike after cake arrives.” Bill studied its picture of a grinning enormous purple dinosaur. “What about security? That dinosaur looks remarkably well fed today.” Molly circled the garden gate with a stolen blue crayon. “We enter disguised as entertainers. Nobody suspects a professional clown.” Bill opened his coat, revealing an arsenal of novelty noses. “I’ve got noses, but my balloon animals are mostly snakes.” Molly nodded, impressed despite his inability to inflate ordinary balloons. “Excellent. Snakes cause panic. Panic clears the present table quickly.” Outside, a passing child paused beneath their open kitchen window. “How many presents can your bicycle basket actually hold, Bill?” Bill consulted a notebook filled exclusively with doodles of large sausages. “Approximately twelve, unless someone’s brought a pony or a trampoline.” The child leaned closer, clutching a small, suspiciously shiny whistle. “We’ll need every gift, including anything hidden under the trampoline.” Suddenly, the whistle shrieked, and tiny footsteps thundered toward them. “Molly, I think the birthday child has brought backup dancers.” Through the window flew cupcakes, followed by a furious pony. “Abort the mission, Bill! The pony’s wearing a police hat!”
