Molly leaned over the rickety kitchen table, blueprints of the backyard sprawled out like a treasure map. Bill paced, twirling a fake mustache. "Listen, Molly, it's genius," Bill said, eyes gleaming. "Rich kid's birthday bash tomorrow. Piñata, cake, pile of presents taller than me. We crash the party, snag the loot, vanish like ghosts." Molly snorted, jabbing a finger at the diagram. "Ghosts? Bill, we're talking squealing brats and clown makeup. How do we blend? Show up as sad-face balloons?" Bill grinned, snapping his fingers. "Disguises! You in a frilly princess gown, me as the magic man with a top hat. We 'entertain' while palming gifts. Quick as a wink—stuff 'em in the van disguised as a bounce house truck." She arched an eyebrow. "And the kids? One spots us rifling through Barbie boxes, we're toast. Or worse, they think we're the piñata and bash us!" "Nah, we spike the punch with sleepy-time juice—kidding! Distraction: I juggle, you decoy with bad karaoke. Boom, presents ours. Think of the haul—Xbox, bikes, that diamond-encrusted teddy bear!" Molly laughed, sketching a escape route. "Fine, but if a toddler tags along in my princess skirt, you're changing diapers. This heist better not end in tears." "Only happy ones—from the parents when they realize Santa came early!" Bill whooped, high-fiving her.
