Molly peered through binoculars, glaring down at Bill’s oversized yellow squeaky shoes. "Are you seriously wearing clown shoes?" Bill adjusted his dark ski mask with extreme professional dignity. "They muffle footsteps on bouncy castles, Molly." Molly snatched the greasy paper napkin from his glove. "That is tactical nonsense, Bill. Hand me the blueprints." Bill tapped a wobbly purple scribble with his small flashlight. "Timmy drew them in crayon. The bounce house is by the patio." She grimaced at the sticky driveway layout. "Where exactly is the birthday loot?" Bill squinted through the van's surveillance scope. "Guarded by a furious mother beside the mahogany gift table." She checked her wristwatch with military precision. "Easy mark. We breach during the magic show." Bill nervously chewed his sugary pink bubblegum. "What if the birthday magician is legit?" She sighed, loading a smoke grenade into her slingshot. "He pulls plastic doves from sleeves, Bill. We grab the wrapped boxes and sprint." Bill grinned broadly, clutching an empty burlap sack. "Dibs on the giant Lego Millennium Falcon." Molly pushed the surveillance van doors open. "Focus! We split the toys evenly, no trades." Bill nodded solemnly, testing his silent shoes. "Fine, but I keep the cake."
