Molly unrolled the blueprint across the stolen ice cream van's dashboard while Bill tried to look inconspicuous in a clown wig that was actively rejecting his scalp. The target was not a bank or a museum but little Timmy Henderson's seventh birthday party, an event rumored to have more wrapped loot per square foot than a department store. The backyard was fortified with bored parents, a hyperactive bouncy castle, and a surprisingly aggressive pony. Their plan relied on Bill posing as the entertainment. Molly had studied the present table for weeks via binoculars from the neighbor's oak, cataloging every rectangular and suspiciously rattling box. She tapped the blueprint with a french fry. Bill adjusted his squeaking red nose and whispered anxiously about the ethics of stealing from children. Molly reminded him that the real score was the limited edition gaming console buried under unicorn wrapping paper. "We need distraction, then grab bags fast before parents notice," she said. "What if pony attacks or kids scream loudly at us?" he replied. Bill swallowed hard as distant children's laughter echoed like an alarm. Molly grinned, already imagining the getaway chased by sugar fueled seven year olds wielding cake and plastic swords angrily.
