Molly adjusted her binoculars and peered through the windshield of their stolen plumbing van. The target was a suburban backyard currently overrun by seventy screaming children. She lowered the heavy lenses, turned to her right, and looked at Bill. He was casually chewing a giant sandwich very loudly. "Are you reviewing the tactical blueprints right now?" Bill wiped a thick glob of mayonnaise from his doubled chin onto his flannel sleeve, swallowed heavily, and proudly shook his large head at her. "I ate them all. You printed the plans on a tortilla." Molly let out a long breath and carefully unrolled a large paper blueprint map across the dusty plastic dashboard. Multiple red marker circles covered the worn paper. "Focus, Bill. We face a hostile perimeter. The bouncy castle is blocking the rear gate." Bill leaned over the center console, smudging the map with his greasy fingers. "We bounce over the wall. Nobody checks the castle. It is a blind spot." Molly sharply swatted his hand away from the map and glared into his eyes. "We are professionals. We do not bounce. We infiltrate, secure the gift table, and extract. Remember the main objective?" He nodded confidently, tapping his temple. "Grab the biggest boxes, avoid the clown, and escape before they serve the cake." She immediately shook her covered head furiously, tightly grabbing him by the fabric of his collar. "We are not leaving before cake. The cake is a secondary objective. It has a dinosaur on it." Bill slowly smiled and chuckled softly. "I stand corrected. How do we bypass the roaming mothers?" She gently released his rumpled shirt and pointed a gloved finger toward a small wooden corral situated directly beside the neighboring house. "I have a distraction. At precisely noon, I will release three greased piglets into the petting zoo. Utter chaos will ensue." Bill excitedly clapped his hands together. "That is brilliant. What is my role during the piglet deployment?" Molly blindly reached into the cluttered back seat and tossed a massive dark fuzzy duffel bag completely onto his lap. "You will wear the mascot costume. When the adults panic, you walk directly to the patio, load the presents into a sack, and meet me at the extraction zone." He poked the synthetic fur. "Which specific animal costume did you actually procure for me?" She grabbed her binoculars again. "A giant purple hippopotamus. It demands absolute and total respect." Bill instantly frowned, aggressively scratching his head. "Will a giant hippo stealing gifts draw attention?" She kept her eyes fixed firmly on the backyard. "Not during a pig crisis. Look, the clown is setting up. We have exactly four minutes to synchronize our watches." He blankly tapped his totally bare wrist twice. "I swallowed my watch last Tuesday." She finally sighed deeply, resting her aching head against the hot steering wheel. "Just follow my lead. Bring the unwrapped presents, constantly check for hostile toddler guards, and do not drop the buttercream dinosaur cake under any circumstances whatsoever."
