Molly hunched over the rickety kitchen table, blueprints of the community center spread out like a treasure map. Bill paced, twirling a fake mustache he'd bought for "disguise purposes." The room smelled of stale coffee and desperation. "Listen, Bill," Molly said, jabbing a finger at the diagram. "We crash the party as the balloon animal clowns. Kids love that crap. I'll twist dachshunds while you pilfer the present pile." Bill snorted, adjusting his mustache. "Brilliant, Mol. But what if the rugrats spot us? One whiff of our sweaty thief vibes, and we're toast. Or worse—covered in cake." She grinned wickedly. "That's why we bring the smoke bombs. Poof! Magical disappearing presents. We load 'em into the van disguised as a bounce house delivery." "Risky," Bill muttered, scratching his chin. "The birthday kid's dad is that burly cop, remember? One wrong move, and we're twisting bars in jail instead of balloons." Molly leaned back, eyes sparkling. "Then we bribe him with a stolen pony ride. Come on, Bill—think of the haul. Toys for days on the black market. We're talking teddy bears to the moon!" Bill chuckled despite himself. "Fine, but if a kid cries, you're handling the waterworks. Deal?" "Deal," she said, clinking her coffee mug against his. The heist was on—chaos and candy awaited.
