"We drop through the inflatable roof at exactly noon sharp." Molly handed the stolen blueprints across the dirty sedan dashboard. "Are you positive about the structural integrity of that castle?" Bill wiped a smear of powdered sugar from his chin. "It is industrial grade vinyl. I read the manufacturer specifications." Molly tapped the grainy photograph of a massive inflatable fortress. "What about securing the actual targets? We have a schedule." Bill squinted at the sunny lawn swarming with screaming children. "The gift table is completely unguarded near the petting zoo." Molly immediately shook her head and pointed her gloved finger. "You are forgetting the hyperactive perimeter guards. I mean toddlers." Bill gasped loud and dropped his pastry on the floorboards. "They are fueled by uncut frosting and pure chaotic energy." Molly nodded gravely while adjusting the tint on her sunglasses. "I brought a tranquilizer dart gun loaded with apple juice." Bill retrieved a bright plastic weapon from his jacket pocket. "Save the heavy artillery for the final extraction phase, please." Molly checked the cylinder of her shiny silver grappling hook. "Do you think the clown is packing concealed balloon animals?" Bill asked while observing the colorful entertainer making a poodle. "We bribed Chuckles yesterday to look away during the raid." Molly smiled as the clown suddenly gave them a wave. "That leaves the primary obstacle. A mother holding a clipboard." Bill shuddered violently against the faded upholstery of the car. "Karen is ruthless. She organized this entire extravaganza with precision." Molly withdrew a small smoke bomb from her tactical vest. "If she catches us taking the presents, she will scream." Bill nervously bit his lower lip and checked his watch. "That is exactly why we deploy the candy diversion first." Molly grinned widely and unspooled a coil of titanium cable. "Will that be enough to empty the patio seating area?" Bill leaned forward to get a better view outside today. "Every single kid in existence will enthusiastically rush for candy." Molly locked the heavy metal hook into her leather harness. "Then I sprint toward the table and bag the boxes." Bill pantomimed scooping up enormous square items into his arms. "Prioritize the largest packages wrapped with the most expensive paper." Molly secured the safety latch and kicked the car door. "Are we really stealing gifts from a tiny little boy?" Bill suddenly slumped backward and covered his face in shame. "His father robbed a grandmother last week at the bank." Molly slid from the vehicle and marched toward the street. "I completely forgot this was actually an elaborate revenge mission." Bill smiled brightly and stepped out to join his partner. "The newest gaming console is inside that shiny blue box." Molly whispered softly while ducking behind a neatly trimmed hedge. "We will be gaming like kings in the hideout tonight." Bill readied his large canvas sack and cracked his knuckles. "Commence the operation. Deploy the festive diversion and grab everything." Molly threw the explosive device directly into the paper donkey.
