Molly and Bill squeezed into the back of their rusty van, parked across from the twinkling lights of the Peterson mansion. Blueprints of the sprawling backyard sprawled across Molly's lap, marked with crayon scribbles from their last "inspiration session." "Alright, Bill, listen up," Molly said, jabbing a finger at the diagram. "We crash the kiddie party as the surprise entertainment duo—'Magical Mischief Makers.' You juggle, I vanish behind the cake, and while the rugrats are mesmerized, we swipe the present pile." Bill snorted, adjusting his fake mustache. "Juggling? With these paws? Last time I tried, I beaned a grandma at a bingo hall. And what about the parents? They'll be hawk-eyed, sipping eggnog and filming everything for TikTok doom." Molly grinned wickedly. "That's why we spike the punch with sleepy-time herbs—nothing lethal, just a nap attack. Then it's grab-and-go in the gift-wrapped getaway sleigh." "Sleigh? In July? You'll look like a deranged Santa reject." "Better than your elf ears idea. We'd get trampled by hyper toddlers before present one." Bill chuckled. "Fine, but if a kiddo clings to my leg yelling 'Uncle Bill!' mid-heist, you're bribing him with candy." "Deal. Now, practice your evil laugh—quietly." As sirens wailed distantly, they high-fived, plotting their pint-sized plunder.
