Molly slouched on the sagging couch in their cramped hideout, blueprints of the suburban mansion spread across the coffee table like a kid's coloring book gone wrong. Bill paced, his oversized trench coat swishing like a deflating balloon. The target: little Timmy Turner's eighth birthday bash, a goldmine of unwrapped treasures from oblivious parents. "Look at this," Molly said, jabbing a finger at the diagram. "Backyard tent, piñata central. Kids'll be distracted by clowns. We slip in as caterers—I've got aprons." Bill snorted, adjusting his fake mustache that kept slipping. "Caterers? With your cooking? One whiff of your chili, and the party's over before we start." She shot him a glare. "Hey, it's foolproof. Grab the gift table while they're blindfolded. Stuff sacks under the punch bowl." "Blindfolded kids and punch? Sounds like a setup for chaos. What if one spots us?" Molly grinned wickedly. "Then we blame the magician. Poof—presents gone." Bill nodded, eyes gleaming. "Alright, Operation Candy Heist launches at noon. No kids harmed, just their holiday cheer." As they high-fived, the room filled with the absurd thrill of plotting against pint-sized joy. Outside, balloons bobbed innocently in the breeze, unaware of the comedic caper brewing.
