"So what is the security situation looking like for the target at the preschool?" Molly asked. "It is formidable. We have a bouncy castle perimeter guarded by two professional clown mercenaries making balloon animals. I suspect the dachshund balloons are actually inflatable drones," Bill said. "Clowns? We did not plan for clowns. Are the presents inside the fortified castle?" she asked. "No, they are piled directly adjacent to the pony pinata. The host parents are drunk on cheap mimosas." "Excellent. What is the loot estimate? Are we talking basic plastic action figures or high end electronics?" "The birthday boy is turning seven today. I saw three wrapped boxes the exact dimensions of a gaming console. We are going to be rich." "What is our grand extraction plan once we secure the toys?" "I will dress as a hired birthday magician. I will throw a giant purple smoke bomb, yell presto, and we grab the entire haul while the sticky toddlers are completely confused." "Will the children cry?" "Probably. Little brat will never get his shiny new bicycle." "Wait, there is a bicycle?" "A red one." "I call the bicycle." "Focus, Molly. We are elite master thieves, not ordinary playground bullies."
