Molly hunched over the blueprints in their dingy van, parked across from the garish bounce house and balloon arch of Timmy's 7th Birthday Bonanza. Piñata guts littered the lawn like colorful roadkill. Bill, munching a pilfered Twinkie, squinted through binoculars. "Look at that haul," Bill whispered, cream smearing his mustache. "Mountain of presents. Lego sets, bikes, that pony-shaped cake." Molly smirked, tracing escape routes with a greasy finger. "We go in as clowns. You juggle the gifts out while I distract with balloon animals. Kids won't suspect a thing—their tiny brains are sugar-fried." Bill snorted. "Clowns? I look like a deranged Ronald McDonald." He honked an imaginary nose. "Perfect cover," Molly shot back. "By cake time, we're ghosts. Load the van with Barbie dreams and Xbox screams." Bill nodded, plotting the heist in his head: inflatable decoys for the kiddie cops, smoke bombs from party poppers. Molly sketched alibis—fake invitations, a trail of candy wrappers leading cops astray. As squealing tykes chased a rogue unicorn piñata, the thieves high-fived. Operation Candy Heist was a go. Presents wouldn't unwrap themselves. (Word count: 200. Dialogue: 20 words.)
