Molly adjusted her oversized glasses, peering at the crumpled flyer for "Timmy's Superhero Bash" pinned to the fridge in their cluttered hideout. Bill paced the linoleum floor, twirling a fake mustache he'd bought for the heist. "This is gold, Mol," Bill said, slapping the table. "Hundreds of presents under that balloon arch. We pose as entertainers—magic tricks with a side of sleight-of-hand gift-grabbing." Molly smirked, sketching a quick map on a napkin. "Right, but the clown's the wildcard. One squirting flower, and we're dodging pies. We time it for the cake smash—kids distracted, parents tipsy on punch." Bill nodded, eyes gleaming. "I'll handle the diversion: fake spider in the punch bowl. You load the swag into the van disguised as the bounce house truck." She laughed, imagining the chaos. "Perfect. No capes for us, just ski masks under party hats. In and out before the piñata pops." As they high-fived, the radio blared kiddie tunes, mocking their devious plot. Molly pocketed the flyer, heart racing with giddy anticipation. Stealing from superheroes? It was villainy at its silliest.
