The surveillance van smelled of damp dog and raspberry sugar. Molly tapped an unsharpened crayon against the crude map. Bill nervously zipped his oversized clown suit, squinting through the foggy peephole at the bouncing castle on the lawn. "Tell me the drop zone is clear." Bill adjusted his red nose with chalky fingers. "The perimeter is crawling with hostiles. I count four toddlers by the swing set and an uncle guarding the barbecue." Molly slammed her fist onto the folding table, rattling two stolen apple juice boxes. "We planned for this. The uncle enters a heavy food coma at two o'clock, giving us an eight minute window." Bill smoothed down his wild green synthetic wig. "I look like a nightmare, Molly. Children will scream." Molly rolled her eyes and pointed impatiently at the map. "You look like an entertainer. Focus on the target." Bill leaned forward over the sticky steering wheel. "Which target is top priority?" She aggressively circled the rear sunroom patio with thick red wax. "The loot on the patio table. We take the remote control helicopter and that massive golden parcel." Bill chewed nervously on the thumb of his giant white glove. "What if that golden parcel only contains winter clothes?" She glared across the dim van. "Grandmother flew from Miami. That box contains expensive electronics." Bill pointed a shaky finger toward the backyard fence. "What about our primary extraction route?" She traced an escape route along the perimeter with crayon. "We slip through the pet door behind the kitchen. I greased the plastic flap with dairy butter this morning." Bill blinked through his heavy layers of clown makeup. "A buttered pet door? What about the family hound?" Molly smirked, crossing her arms with absolute and total confidence. "I neutralized the beast. A pound of roasted ham is keeping him delightfully distracted in the garage." Bill peered outside through the peephole. "What about the hanging donkey?" She tapped the hasty diagram of the maple tree firmly. "That is our diversion. When the mob attacks the candy, we bag the presents." Bill patted down the bright satin fabric of his trousers. "These clown trousers have no pockets." She produced a canvas laundry sack from beneath the metal passenger bench. "You will carry the reinforced canvas sack. No excuses, no whining, and absolutely no balloon animals." He pouted behind his painted bright red smile. "Not even one tiny balloon dachshund?" Her sharp glare hardened into pure and unforgiving criminal steel. "If I hear one squeak of twisted latex, I will abandon you inside the plastic ball pit." He checked the silver watch strapped to his wrist. "Fair enough. When do we strike?" Molly grabbed the rusty metal side door handle with determination. "The birthday candles are lit in sixty seconds. Put on your giant wig and move." Bill adjusted his rainbow wig with a heavy, tragic sigh. "Time to ruin a seven year old boy's afternoon." Molly pulled her dark mask down and shoved him into the blinding sunlight.
