"Listen to me, Bill. We hit the bouncy castle at exactly noon. That is when the sugar crash begins." Molly whispered. "I still think the clown is a wild card. What if he makes a balloon dog out of my lockpicks?" Bill fidgeted nervously. "He is an entertainer, not a wizard. We slip past the petting zoo, flank the juice box station, and infiltrate the gift pile during the magic show. The paper creates perfect cover." Molly stated. "But what about the birthday boy? Timmy has eyes like a hawk, Molly. He saw me casing the cupcakes yesterday. He knows my face!" Bill sighed heavily. "Timmy is seven. I bribed him with a shiny red tractor toy. Once he yells about a missing wheel, total panic erupts. We bag the Legos, grab the action figures, and extract through the sliding doors immediately." Molly smiled proudly. "Do we actually steal the wrapping paper?" Bill asked. "Obviously. We are professionals, we leave absolutely no evidence behind. Put on those oversized squeaky shoes right now." Molly demanded clearly. "These squeak too violently." Bill groaned. "That is our tactical advantage. They will merely assume we are part of the circus troupe. Let us roll."
