Molly spread the blueprint across the kitchen table, which was actually just a crayon drawing stolen from the birthday boy's fridge. Bill squinted at the lopsided castle, the stick figures, and the giant red X marking the present table. Their plan required precision, ridiculous costumes, and absolute silence around hyperactive seven year olds. Molly tapped the drawing. "We enter through the back gate at three." Bill nodded solemnly, adjusting his ill-fitting clown wig. "I'll distract the clown, you grab loot." Molly frowned, considering the terrifying bouncy castle guarding the yard. "The castle is the vault." Bill shivered and stared at the ominous inflatable dragon entrance. Molly grinned and revealed juice boxes laced with sugar to create chaos. She had packed extra sprinkles while Bill's oversized shoes squeaked with every nervous step, threatening to betray them instantly. The heist would demand stealth, speed, and immunity to screaming, crying, and sticky frosting ambushes lurking near the cake. Outside, balloons bobbed ominously and a distant chorus of children screaming happy birthday signaled impending doom. Bill checked his watch, Molly tightened her ponytail, and both stared at the pile of brightly wrapped boxes waiting to be liberated. They were ready for glory. Almost ready.
