Molly hunched over the rickety kitchen table in their dimly lit apartment, blueprints of the neighborhood spread out like a treasure map for toddlers. Pinwheels and balloon strings doodled in the margins hinted at the absurdity of their latest scheme. Bill paced, his oversized trench coat dragging on the floor, munching on a pilfered candy bar. "Think about it, Bill," Molly said, jabbing a finger at the sketch of the backyard party. "Kids' presents—easy marks. No alarms, just sticky fingers and sugar highs." Bill nodded, crumbs tumbling from his lips. "Yeah, but what if the clown spots us? We go in as... what, party crashers?" "Exactly. I'll be the face-painter, you the balloon animal guy. Swoop in, stuff the gifts in our 'magic' bags, and vanish like Houdini with a piñata." Bill snorted, sketching a quick escape route involving a bouncy castle as cover. "Risky. One wrong twist, and we're dodging dodgeballs from hyper rugrats." Molly grinned, eyes gleaming with mischief. "That's the thrill. Presents galore—Lego sets, bikes, the works. We'll fence 'em for a fortune." As they huddled closer, the plan solidified amid laughter, the air thick with the scent of impending chaos. Little did they know, the real heist would unravel faster than a cheap party streamer.
