Molly and Bill sat huddled in the cramped alleyway, scouring the plans of the party venue. The birthday boy's affluent parents had spared no expense, and the guest list was a veritable who's who of the city's elite. The real prize, however, was the tantalizing treasure trove of pricey gifts that would be gathered in the party's designated "Present Palace." Molly's eyes sparkled with mischief as she circled a ventilation shaft on the diagram. "This is our way in. Bill, can you work your magic on the ductwork?" Bill, a master of unsavory expertise, grinned lazily. "Child's play, Molly. I'll have us crawling like snakes through the air vents in no time." As they pored over the plans, Molly's gaze lingered on the schedule of events. "Okay, the party's scheduled to start at 3 pm. We'll need to move fast to grab the loot before the kiddos get to the presents." Bill nodded, a faraway look in his eye. "I'm thinking we can use the ' Lost Balloon' distraction. You know, create a diversion with a stray balloon, and while the parents are chasing it down, we make our move." Molly chuckled, a sly glint in her own eye. "You always were a master of misdirection, Bill. Now, let's get to work and make this birthday party one to remember."
