"The target is heavily fortified." Bill tapped a crayon against the crumpled piece of loose paper. "It is exactly a bouncy castle." Molly adjusted her black sweater collar and squinted down at the drawing. "They have a scary clown." He lowered his scratchy voice to a truly terrified and quiet whisper. "We have dealt with big security teams before." She pulled out a monocle and placed it over her left eye. "Not like this guy. His name is Sparkles. He makes balloon animals out of pure malice." Bill pointed frantically at a crude stick figure drawn near the yard. "Focus on the valuable loot. Where is the present table?" She tapped the paper map lightly with a single gloved index finger. "Right next to the juice cooler." He traced a path straight through the horribly overgrown green front grass. "That is a major choke point." Molly frowned deeply and proceeded to cross her arms in tactical defense. "Exactly. We have to breach the perimeter during the main candy strike." He grinned broadly to proudly reveal a noticeably chipped yellow front tooth. "The young children will be fully distracted by all the falling sweets." She nodded in solemn approval, internally calculating the strict timing requirements easily. "The little brats will not notice us safely moving the wrapped packages." Bill rubbed his sweaty palms together with absolute and unbridled gleeful anticipation. "What if the birthday boy manages to catch us?" Molly asked calmly while visually scanning the violently busy suburban street scene. "Timmy is turning six. He lacks the upper body strength to fight." He puffed out his remarkably frail chest with entirely fabricated thief confidence. "Do you have the diversion ready?" She checked her silver pocket watch to strictly monitor their impending deadline. "I hired stray dogs to chase a laser across the inflatable slide." He smiled, nervously wiping a massive rolling bead of cold sweat away. "Brilliant. We swoop down, grab the plastic blocks effortlessly, and quickly vanish." She patted his shoulder lightly to offer some much needed false reassurance. "I genuinely hope there is a fast toy car tucked safely inside one of those large boxes." Bill stared wistfully out the cracked window of their rusted surveillance vehicle. "You are supposed to be a hardened professional. Start acting like it." Molly severely slapped the back of his bald head with a magazine. "Even seasoned professionals casually enjoy a really good toy. My old one broke last week during the major bank job." He rubbed his neck. "Do not lose focus. We quickly secure the bags, load the trunk, and extract immediately." She grabbed her shiny keys and slipped them into a canvas pouch. "Are we realistically still firmly disguised as the main party musical entertainment?" Bill lifted giant floppy shoes. "We are the magicians. Put on your vest so we can finally steal." She tossed violently bright fabric directly into his unamused, exhausted face. "I cannot breathe in this thing. The buttons are too unbelievably tight." He complained aloud.
