Molly hunched over the kitchen table, blueprints of "Little Timmy's Super-Duper Birthday Bash" spread out like a treasure map. Pinwheels and balloon sketches dotted the venue layout at the community center. Bill paced, twirling a fake mustache he'd glued on crookedly. "Perfect cover," Molly whispered, circling the gift table in red ink. "Two hundred screaming kids, distracted parents, piles of shiny presents ripe for the taking." Bill nodded, tripping over a chair. "We slip in as party entertainers. I juggle, you do magic. Swap the loot into these duffel bags disguised as balloon animals." Molly smirked, sketching escape routes past the bounce house. "Piñata distraction at 3 PM sharp. Kids swarm candy, we dash with the haul—Xbox, bikes, that pony someone’s nuts enough to gift." "Timing's key," Bill said, eyes gleaming. "In at cake-cutting, out before the tears." Molly: "Dress as clowns?" Bill: "Yeah! Grab gifts during Happy Birthday!" She high-fived him, ignoring the mustache peeling off. Sirens wailed outside—false alarm, just an ice cream truck. They cackled, toasting with lukewarm coffee. The heist of the century: raiding tots for toys. What could go wrong?
