Molly crouched behind the hedge opposite the bouncy castle, wearing a penguin costume two sizes too small and the expression of a tax auditor at a cupcake buffet. Bill unfolded their map, which was actually a napkin smeared with frosting and one alarming drawing of a dragon. "Remember, we enter as magicians, distract toddlers, grab gifts, vanish before cake." Molly adjusted her flippers. "You're Professor Pudding; I'm the emotional support penguin." Across the lawn, children shrieked around a piƱata shaped like a unicorn with legal representation. The present table glittered beneath balloons, a mountain of ribbons, dinosaurs, dolls, and one suspiciously adult-sized box humming softly. Bill tapped the napkin. Phase One: produce rabbit. Phase Two: rabbit refuses. Phase Three: improvisation. Molly had prepared smoke pellets, lock picks, and apologetic stickers reading SORRY ABOUT THE FELONY. Bill had brought a wand, three raisins, and confidence, which Molly considered the most dangerous tool. A grandmother glanced their way. Molly froze, then waddled magnificently, waving like royalty. The grandmother applauded. Bill whispered that the plan was working. Then the adult-sized box sneezed. From inside came a small voice demanding union rates, hazard pay, and first choice of any present containing batteries today immediately.
