Molly crouched behind the hedgerow, peering through a gap at the bouncy castle rocking with sugar-crazed children. Bill knelt beside her, fiddling with a comically oversized pair of pliers. “This is the worst idea we’ve ever had,” Molly whispered, “and we once robbed a bank dressed as clowns.” Bill grinned, eyes gleaming with criminal joy. “Exactly. No one suspects the cartoon tigers at a six-year-old’s party. We slip in, swap the presents for our weighted decoys, and waddle out heroes. Or tigers. Whatever.” Molly rolled her eyes so hard her ski mask slipped. “If we get caught, I’m telling the cops you kidnapped me.” “Relax,” Bill said, checking his novelty watch shaped like a duck. “We hit the gift table at peak cake chaos. You create the distraction with the whoopee cushion, I bag the goods. Easy as stealing candy from—well, you know.” She sighed, adjusting her striped tail. “Fine. But if I have to sing ‘Happy Birthday’ I’m keeping the PlayStation.” Bill offered her a paw. “Partners?” Molly slapped it away. “Only until we fence the Barbie Dreamhouse.” They crept forward, two ridiculous figures about to commit the most humiliating felony of their careers.
