Molly and Bill squeezed into a rusty van parked across from the suburban McMansion, blueprints of the backyard party spread across the dashboard like a picnic gone wrong. Streamers and balloons bobbed in the breeze, promising a haul of shiny toys ripe for the taking. "Bill, look at this spread," Molly whispered, jabbing a finger at the flyer. "Timmy's turning five—parents loaded, kids oblivious. We hit at cake time, grab the gift table, and vanish." Bill scratched his stubbled chin, eyes wide. "Kids? Screaming hordes? We'll need disguises. Clowns?" Molly snorted. "Clowns? Genius! Red noses, floppy shoes. I'll juggle the presents out while you distract with balloon animals." "What if the piñata foils us?" Bill fretted. "One whack, candy explosion—chaos!" "Perfect cover!" Molly grinned. "We 'accidentally' smash it early, scoop toys amid the frenzy. Pin the tail on the donkey? Nah, pin the loot on the thieves." Bill chuckled nervously. "And the cake? Evidence trail?" "Eat it," Molly said. "Or blame the dog. In, out in five—richest kiddie heist ever." Bill nodded, pumping a fist. "To the sugarplum plunder!" As sirens wailed distantly—fireworks test?—they high-fived, plotting their pint-sized perfect crime.
