Molly hunched over the cluttered kitchen table, blueprints of "Little Timmy's Super-Duper Birthday Bash" spread like a treasure map. Pinatas dangled from the fridge, mocking their scheme. Bill paced, twirling a fake mustache. "Perfect score," Molly whispered, eyes gleaming. "Hundred kids, richer parents—presents piled high. We hit at cake time." Bill snorted, nearly tripping over a whoopee cushion. "Cake time? Chaos! But how? Guards—er, parents—everywhere." Molly grinned, holding up floppy clown shoes. "We go in as entertainers. I juggle, you twist balloons into gift bags. Swoop 'em while they squeal." "Juggling thieves? Genius!" Bill barked a laugh. "I'll be 'Uncle Bill the Balloon Bandit.' Kids love me." "Love you? Last time you 'entertained,' you popped the cake!" Molly jabbed. Bill puffed up. "Details. We need diversions: fake piñata with glitter bombs. Exit via bounce house tunnel." Molly sketched the route, cackling. Visions danced—sacks bulging with Barbies, Xboxes, Lego empires. Sirens? Nah, who'd suspect clowns fleeing a toddler tantrum? Bill high-fived her. "Tonight, we rob joy itself. To heisting happiness!" As dawn crept, their giggles echoed. The party palace awaited its pint-sized plunder.
