"Is the target secure inside the bouncy castle?" Molly whispered quietly. "Yes. Kindergartners have terrible perimeter defense. Mostly juice boxes." Bill nodded slowly. "And the secured loot?" Molly asked. "Wrapped in shiny paper. Legos, dolls, and remote toys. A true goldmine." Bill grinned. "What about the stupid clown?" "Distracted. He is making a balloon giraffe that resembles a poodle." "Perfect. We strike during cake cutting. The sugar rush creates maximum chaos." "I will wear the sombrero. You take the princess dress." Bill offered. "Why do I always have to be the magical princess?" Molly sighed. "Because you can sing the song if parents get suspicious. I sound like a dying walrus." "Fine. Grab the sack. If a toddler interrogates us, tell them we are the official Department of Gift Inspection." "Department of Gift Inspection. Understood. Should I bring the smoke grenades?" Bill asked. "No smoke grenades. Just smile, nod, and carry the presents out the back door." Molly pointed. "What if the birthday boy tries to stop us?" "I brought a giant lollipop to bribe him. Do not step on the piƱata." "Obviously. I am a highly trained professional. I only steal from toddlers with absolute undeniable grace." Bill winked.
