Molly tapped the crayon map on the sticky table, scanning the layout. "Are you certain the target is a child's birthday party?" Bill adjusted his black turtleneck, the heist uniform, and sipped coffee. "The payout is massive. Timmy is getting a PlayStation. Prime fencing material." Molly stared at the drawing of a bouncy castle, tracing the perimeter with a pencil. "It is a children's party, Bill. There will be clowns." Bill leaned forward, eyes narrowing with intense focus. "Which is why we go in as entertainment. I have the clown car ready." Molly dropped the pencil and crossed her arms, glaring at her partner. "You bought a clown car? How do we make a fast getaway in that thing?" Bill waved a dismissive hand, knocking over the sugar dispenser. "It is all about the illusion, Molly. Nobody suspects the sad clown." She rubbed her temples, feeling a headache blossoming behind her eyes. "What about the perimeter security? I heard they rented a castle." Bill pulled a massive, brightly colored inflatable hammer from his duffel bag and squeezed it. "I have the tactical inflatable hammer. I can neutralize the castle guards in under ten seconds." Molly stared at the plastic weapon in sheer disbelief. "The guards are seven year olds, Bill." He put the hammer away, expression dead serious as he pointed at the map. "Vicious seven year olds hopped on cake. We hit the gift table at fourteen hundred, right after the piƱata. The parents will be too busy to notice." Molly chewed her lip, running the timing through her head. Risky. "Fine. But what about the unicorn?" Bill choked on his coffee, spilling a dark puddle onto the map. "What unicorn?" She tapped the blueprint corner where a tiny horned horse had been scribbled. "The petting zoo. A pony with a horn glued to its head. It could blow our cover." Bill mopped up the spill with a look of intense concentration, his mind clearly racing. "I will bring apples. The pony gets an apple, we get the loot." Molly shook her head, envisioning the absolute disaster this was going to become. "Nothing is foolproof with glitter. They have cannons, Bill. We will leave a trail to the safe house." Bill leaned back, a confident smirk spreading across his face as he crumpled a napkin. "That is why we wear coveralls. We strip them off in the car and incinerate the evidence." Molly folded the map and tucked it into her leather jacket, accepting her grim fate. "I cannot believe I am agreeing to this." Bill threw a crumpled ten dollar bill onto the table, his chest puffing up with pride. "By tomorrow, we will be the best thieves around, and Timmy will learn a lesson about reality." She slid out of the booth, grabbing the inflatable hammer from the seat. "Just remember to tie your balloon animals. Last time, the poodle exploded and you took out a grandmother."
