Molly crouched behind the hedge, peering at the bouncy castle where shrieking kids waved neon party bags. Bill adjusted his comically small party hat, looking more like a hungover birthday clown than a master thief. "We go in during musical chairs," Molly whispered. "The presents are stacked by the cake table like a glittering pyramid of opportunity." Bill grinned, cheeks bulging with stolen cupcake. "You distract the magician, I'll swap the gift bags with our empty ones. Those little monsters won't notice till they're unwrapping socks." "Remember the decoy," she said, checking her watch. "When the piƱata breaks, we vanish in the candy chaos. Ten seconds max." "Piece of cake," Bill chuckled. "Literally. I ate three already." Molly rolled her eyes. "Focus, Bill. This isn't just any job. We're stealing Christmas from thirty screaming six-year-olds. If we pull this off, it'll be the most diabolical heist in suburban legend." He winked, gripping his goody-bag disguise. "For the record, I still think dressing as the hired entertainers was brilliant. Who suspects the guy in the fuzzy bear suit?" They high-fived silently, then slipped toward the laughter, two shadows hunting presents in a pastel battlefield of balloons and juice boxes.
