Molly leaned over the crumpled party invite, squinting. "Bill, a kids' birthday bash at old man Hargrove's? Stealing presents from snot-nosed brats? You're off your rocker." Bill grinned, waving a clown wig. "Genius, Mol! Disguises: I'm Bozo the Birthday Bandit, you're Sparkles the Sadistic Sidekick. We crash as entertainers—piñata whack, cake smash, then snag the gift mountain while they're blinded by candy!" "Piñata? Those rugrats'll mob us!" Molly snorted. "And parents? Hyped-up soccer moms with wine breath?" "Distraction city! I rig the piñata with smoke bombs—poof, chaos. You balloon-animal the gifts into duffels. Pin the tail on the donkey? We blindfold 'em extra long." Molly smirked. "Getaway? Unicorn bounce house as cover?" "Nah, cake-faced piñata mule stuffed with loot. Speed off in the clown van—honk honk, suckers!" "Bill, if a toddler IDs us..." "We bribe with stolen Legos! Richest haul ever—no alarms, just tears and giggles." Molly sighed, grabbing the wig. "Fine, Bozo. But if I trip on streamers, you're eating the evidence." Bill whooped. "To the party, Sparkles! Candy-coated caper awaits!"
