Molly and Bill crouched in the shadows of their dingy van, blueprints of "Timmy's Superhero Bash" spread across the dashboard like a treasure map. Molly's eyes gleamed with mischief, her fingers tracing the cake table. "Listen up, Bill," Molly whispered, grinning wickedly. "We hit the party at peak piñata chaos. I go in as the balloon lady—big hat, bigger distractions. You? The face-painter with a fake mustache that itches like hell." Bill snorted, adjusting his oversized bowtie prop. "Genius! While the rugrats chase my butterfly designs, you stuff presents into this duffel disguised as a gift bag. But what about the parents? That Karen mom looks ready to tase clowns." Molly cackled, pulling out a squirting flower. "Easy! Hypno-squirt 'em with fizzy punch. They think it's a prank. We bolt with the loot during the limbo contest—limbo low, getaway high!" Bill rubbed his chin, eyes wide. "Risky. What if a kid cries? Or worse, wants an encore?" "Pfft, we'll autograph the mess!" Molly high-fived him. "Presents for fences by midnight. World's goofiest heist!" Bill nodded, chuckling. "You're a madwoman, Mol. Let's clown around." Outside, party music thumped faintly, their laughter echoing like impending doom.
