Molly adjusted the ski mask over her eyes and glanced nervously at Bill. "You sure this is the right house?" Bill squinted at the colorful banner hanging above the front door. "Positive. 'Happy Birthday, Timmy!' it says. And look, balloons and everything." Molly nodded, her grip tightening on the duffel bag slung over her shoulder. "Okay, let's do this. Remember the plan?" Bill grinned beneath his mask. "Of course. We'll sneak in through the back, grab as many presents as we can carry, and hightail it out of there before anyone notices." "Right. And if anyone does see us, we'll just pretend we're part of the entertainment." "Got it." Bill pulled out a pair of clown noses and handed one to Molly. "Just in case." The two thieves made their way around to the back of the house, where they found a conveniently open window leading into the kitchen. Molly boosted Bill up, and he helped her inside. They crouched low, listening for any sounds of activity. Hearing none, they cautiously made their way towards the living room. As they approached the doorway, they could hear the noise of a large group of children playing. Molly peered around the corner and saw a room decorated with streamers and party hats. A large pile of presents sat beneath a giant inflatable castle. Molly turned back to Bill and gave him a thumbs up. "Coast is clear. Let's move fast." They quickly made their way across the room, trying to avoid drawing attention to themselves. Molly stuffed as many presents as she could into her bag, while Bill grabbed a giant stuffed bear and tucked it under his arm. Just as they were turning to leave, they heard the sound of footsteps approaching. Molly's heart lurched in her chest, and she looked frantically around for a place to hide. A woman's voice called out, "Can I help you with something?" Molly froze, but Bill quickly stepped forward, putting on his best innocent face. "Oh no, we're just here for the party. We're supposed to be the balloon animals." The woman eyed them suspiciously. "Balloon animals? I don't remember hiring anyone for that." "Oh, it's a surprise," Molly chimed in, adopting the same casual tone. "From Timmy's grandma." The woman's expression softened slightly. "Well, I suppose that could be true. But I'm afraid you'll have to wait outside for the other entertainers to arrive. The children are busy playing right now." Bill nodded, trying to look as dejected as possible. "Of course, we understand. We'll just wait out back." As they retreated towards the kitchen, Molly could hear the woman muttering to herself, "I hope grandma didn't forget to mention this to me..." Once they were safely outside, Molly let out a sigh of relief. "That was too close. Let's get out of here before anyone else sees us." Bill grinned, hoisting the giant stuffed bear onto his shoulder. "Relax, we got the biggest prize of all. Look at this thing - it's practically its own heist!" Molly couldn't help but laugh as they made their way back to the car, their mission accomplished. "You know what they say, Bill. Go big or go home." "Exactly." Bill gave the stuffed bear a pat on the head. "And this guy's going to make us a fortune."
