Molly and Bill crouched in the shadows of their rusty van, binoculars trained on the riotous children's party across the street. Streamers tangled like festive spiderwebs, and a horde of sugar-fueled gremlins rampaged around a bouncy castle shaped like a dinosaur. The gift table groaned under a mountain of shiny-wrapped loot: bikes, dolls, gadgets galore. Molly, her face smeared with greasepaint camouflage, unrolled a napkin sketch of the chaos. "Phase one: crash as balloon animals. Kids'll swarm us." Bill nodded, stuffing fake noses into his pockets. "Then piñata whack—grab presents mid-candy storm." She traced the escape route with a candy-striped pencil. "Parents distracted by face-painting clown—me. You rig the cake with itching powder. Instant itch-fest." Bill snorted, envisioning the pandemonium. "Genius. But the birthday tyrant's got a guard dog: fluffy pony." "Pony treats in my bra," Molly winked. "Lure and load the van." He sketched a getaway diagram on a pizza box. "Two minutes max. We're ghosts by cake-smash." They clinked root beer cans, eyes gleaming with larcenous glee. The heist promised slapstick glory: dodging toddlers, outwitting soccer moms, vanishing with a haul worth a candy empire. Innocence was about to get fleeced.
