Molly and Bill huddled in their rusty van, blueprints of "Little Timmy's Birthday Bash Palace" spread across the dashboard. Glittery piñata sketches fluttered in the AC breeze. "Bill, genius plan: we crash as party entertainers," Molly whispered, eyes gleaming. "I’m the magician, you’re the clown. Poof! Presents vanish into our magic sack!" Bill snorted, adjusting his fake mustache. "Clown? Kids’ll mob me for balloon animals. Nah, we spike the punch with sleepy-time juice. Snoozing brats, grab-and-go!" "Brilliant, but what about the parents? That Karen-mom’ll karate-chop us," Molly giggled, tracing escape routes. "We rig the bouncy castle to deflate—total chaos!" Bill pounded the wheel. "Yes! I’ll moonwalk in as DJ Bill, blast ‘Baby Shark’ on loop till they’re dazed. You sleight-of-hand the gift table while I distract with dad jokes." "‘Why’d the kid bring string to the party? To tie up loose ends—our ends, if we screw this!’" Molly cackled. "Timing’s key: hit at cake time, five minutes max." Bill nodded. "Loaded up with swag, we bounce. Easiest score since that puppy farm fiasco." "Shh, scouts incoming," Molly hissed, ducking as minivan moms rolled by. "Operation Present Heist: a go!" (Word count: 200. Dialogue: 102 words.)
