Molly gripped the blueprints like they were state secrets while Bill paced the tiny motel room in mismatched socks. “Okay, genius. We hit the bouncy castle at precisely 3:17. That’s when the clown starts his balloon-animal routine. Maximum distraction.” Bill snorted. “You want me to dress as a dinosaur again? Last time the tail got stuck in the hedge.” “Skip the costume. We go in as disgruntled parents complaining about nut allergies,” Molly said, tapping the paper. “You create a scene by the juice boxes. I slip into the gift pile, swap the real presents for identical empty boxes wrapped in the same paper. Thirty seconds tops.” “Thirty seconds? That piñata’s swinging like a wrecking ball, Mol. One wrong move and we’re buried under glitter and screaming six-year-olds.” “Which is why you bring the emergency whoopee cushion. Instant chaos. While they’re all laughing at your gaseous masterpiece, I’m out the back with two trash bags of Barbies and LEGO sets.” Bill rubbed his chin. “We’re going to hell for this, you know.” Molly grinned. “Only if we forget the goodie bags. Those tiny chocolate bars are basically currency in prison.” “Fine. But I’m not wearing the dinosaur suit.”
