Molly pressed the blueprints against the van window while Bill steered with his knees. "Listen, Bill, there are twenty screaming six-year-olds in there. That's basically laser security." Bill snorted and nearly dropped a juice box. "So what's the plan? We walk in as clowns?" "Better. You're the magician. I'm your incredibly reluctant rabbit." Molly tapped the bouncy castle on the map. "The presents are stacked by the cake. We go in during musical chairs." "Right, because no one notices two adults fighting toddlers for chairs." "Exactly. Grab the loot while they're distracted. Then we vanish." Bill frowned at his oversized shoes. "What if the birthday boy cries? I can't handle crying." "Then we give him back one present. We have standards." Molly folded the blueprints into a paper crown and placed it on Bill's head solemnly. "Perfect. Now you look like you belong at a hostage negotiation with juice." Bill adjusted the crown, sighed deeply, and started rehearsing balloon animals with menace. "Let's roll." The van smelled of old frosting and bad decisions. Outside, parents parked minivans, oblivious to the criminal masterminds discussing larceny beside a trampoline. Molly checked her watch. Two hours until cake, chaos, and the greatest toy heist ever attempted. Both thieves nodded, terrified and weirdly excited. Ready for disaster.
