The blueprint was drawn on a stained diner placemat in purple crayon. Molly tapped the poorly sketched octagon with the blunt end of a candy cane. "The bounce house provides visual cover. Security will be sloppy after the pinata drop, Bill. That gives us three whole minutes to hit the loot table." Bill scratched his unshaven jaw and groaned, adjusting a pair of night vision goggles hopelessly tangled in festive paper streamers. "You are forgetting the clown, Molly. Chuckles was discharged from the circus under mysterious circumstances. He has eyes everywhere, especially when sculpting balloon dachshunds." Molly rolled her eyes and crossed her arms over her chest, utterly unimpressed by the supposed threat of a regional entertainer. "Chuckles will be distracted by the glitter explosion. Timmy turns seven at fourteen hundred hours. When the candles are blown, the smoke alarms trip. That is our cue." Bill leaned closer to the perimeter sketch, pointing a trembling finger at the patio. "And the suburban mothers? They run on pure espresso and maternal fury. If Mrs. Henderson spots us, she will tackle us into the ball pit." Molly smiled, pulling two ridiculous plush suits out of a battered duffel bag and tossing the larger one directly into Bill’s lap. "They will be arguing about dairy frosting. Nobody suspects two professional operatives disguised as oversized woodland creatures." Bill rubbed the synthetic fur between his thumb and forefinger with deep skepticism. "I hate chipmunks. The tail ruins my center of gravity. Why cannot we just disguise ourselves as magicians?" She smacked the back of his head with a rolled paper catalog. "Because magicians perform tricks! You cannot even juggle oranges, let alone escape police handcuffs." Bill rubbed his bruised skull, staring sulkily at the crayon map of the Henderson backyard. "What kind of score are we even chasing? Plastic dump trucks? A jar of sticky pennies?" Molly lowered her voice to an intense, conspiratorial whisper, leaning across the small table until her nose nearly touched his. "Timmy’s uncle imported a rare Japanese robotics kit worth thousands. Plus, the grandmother stuffs crisp hundred dollar bills into cards." Bill sat up straighter, sudden greed brightening his weary eyes as he nodded slowly. "Now that sounds like real money. What about the getaway?" She pointed out the window toward the hedge, where two rusted pedals gleamed under the sun. "A tandem bicycle with reinforced baskets. Silent, efficient, completely green." Bill swallowed hard, remembering the terrifying beast guarding the back gate of the estate. "Sir Pawsalot patrols the lawn. That giant poodle is a vicious biter." She casually produced three thick strips of cured pork from her jacket pocket, waving them triumphantly in the air like a prized trophy. "Peanut butter bacon strips. The hound will sleep like babies." "Ten minutes until cake. Are you sure about this?" Bill checked his watch nervously. Molly hoisted the massive chipmunk head over her ears, winking through the plastic mesh mouth. "Grab the burlap sacks. We are going to ruin this birthday."
