Molly perched on the edge of the rooftop, her legs swinging casually, despite the dizzying height. She adjusted her cat-eye goggles, a sly smile creeping across her face. "So, Bill, my old pal. Are you ready for tonight's little adventure?" Bill, busy tinkering with a strange contraption made of springs and colorful party horns, jumped at the sound of her voice. "Molly! Don't sneak up on me like that! And yes, I think so. This party popper-turned-distraction device should do the trick." "That's a good thing, seeing as the party starts in an hour." She checked her toolkit, lined with various tools and gadgets. "We'll be the best 'uninvited guests' they never saw coming." Bill grinned, his eyes sparkling with mischief. "Oh, the looks on those kids' faces when they see us in action. 'Cause who crashes a six-year-old's party dressed as superheroes? Genius, that's who." "Indeed. And while those poor kids are still in shock, we scoop up all the presents, just like that." Molly snapped her fingers dramatically. "But we must ensure the children remain unharmed." Bill's voice lowered to a more serious tone. "No child loses their present on our watch." "Agreed. Now, let's review the plan one more time, ensure every bounce house, face painter, and cotton-candy vendor is accounted for." As the sun began its descent, painting the sky with hues of pink and orange, the dynamic duo double-checked their gear, ready to descend upon the unsuspecting celebration.
