Molly and Bill huddled in their cluttered van, parked across from the suburban McMansion pulsing with birthday balloons. A giant inflatable unicorn bobbed mockingly above the backyard fence, guarding what intel called a "present avalanche"—Lego sets, bikes, and gadgets worth a small fortune. Molly unrolled a napkin map, crayon-scribbled with entry points. "Clowns, Bill. We go in as clowns at cake time." Bill paled, fingering his fake red nose. "Clowns? Kids'll swarm us!" She smirked, outlining the grab: slip through the bounce house flap during the piñata frenzy, stuff a duffel with gift-wrapped loot while hyper toddlers chased candy. Parents too busy filming to notice. "Backup?" Bill whimpered. "Exploding whoopee cushions," Molly whispered. "Diversion city." He nodded, sketching a getaway route past the face-paint tent. They'd pose as entertainers, hired last-minute via a forged flyer. Load the van disguised as a party rental truck, peel out amid confetti chaos. Bill tested his honk-horn shoe—squeak!—and winced. Molly high-fived him. The sugar-rush pandemonium would be their cloak. By sunset, they'd fence the haul at Pawn-o-Rama, laughing all the way to margaritas. One snag: Bill's clown phobia. But hey, therapy was for losers. Heist o'clock ticked nearer.
