Bill unrolled the blueprints. "The target is officially turning six." Molly squinted at them. "Seven. It is a superhero theme, so wear the cape." Bill tapped the paper. "I refuse to wear a cape. I will trip while carrying stolen Lego sets." "The cape is mandatory camouflage among the toddlers. How is the bouncy castle perimeter?" "Guarded by heavily caffeinated clowns. We bypass them through the petting zoo." "What about the aggressive alpacas?" "I bribed them with premium carrots. The asset is a mountain of wrapped boxes next to the chocolate fountain." "How do we logically extract them without triggering a massive tantrum?" "We load everything into our fake piƱata delivery van. Do you have the balloon diversion ready?" Molly loaded her dart gun. "I folded three poodles. It buys us forty seconds of chaos." "Perfect. When I yell about an escaping pony, grab the biggest boxes. Ignore the envelopes." "Ignore the cash? Are you crazy?" Bill nodded once. "Grandma gives five dollar bills. We want the hoverboards. Resale value is huge." "Genius. Do we logically steal the giant birthday cake too?" "Only if it is heavily frosted ice cream. I am a professional thief, Molly, not an absolute monster."
