At midnight, Molly and Bill crouched behind a hedge outside the community hall, where a children's party blazed with balloons, frosting, and suspiciously generous gift-wrapping. “Remember: we enter disguised as entertainers, locate the presents, and leave before the cake explodes.” “What if children recognize us?” Bill adjusted his borrowed magician's hat, which was too small and contained a live hamster. The hamster, named Tax Evasion, had been promised sunflower seeds but received only lint. It expressed its displeasure by chewing through Bill's fake mustache. Molly unfolded the floor plan, drawn on a napkin beside a diagram of the emergency cupcake exits. Their route was elegant: enter through the clown's supply closet, distract the parents with an interpretive dance, and load presents into the inflatable unicorn. Unfortunately, the unicorn had a strict weight limit and squeaked whenever anyone lied. Bill tested it with a single teddy bear. It squeaked, startling three nearby pigeons and a security guard dressed as a pirate. The guard demanded credentials with a sternly raised eyebrow. Molly produced a laminated card identifying them as “Professional Balloon Consultants,” while Bill accidentally presented his library card, expired in 2014. Guard waved them inside, impressed by balloons. Inside, children shrieked around a piñata, parents filmed everything, and Tax Evasion escaped toward the cake. The heist had begun, though nobody had planned for frosting-related casualties.
