Molly and Bill hid in the bushes near the children's party, watching the fun with keen eyes. The yard was full of balloons, games, and a huge pile of presents that called to them like a siren's song. After their last heist failed, they had no choice but to target this celebration for its bounty of toys and gadgets. Their disguises were ready, complete with red noses and floppy shoes. Bill would juggle to draw attention while Molly sneaked the gifts into their sack. They had mapped out every detail, from the timing of the cake cutting to the best escape path through the neighbor's yard. The whole idea was so ridiculous that they couldn't stop laughing about it, yet it might just work if they stayed focused. "We strike when they cut the cake," Molly murmured to her companion. "You distract the little ones with jokes while I load up the bags." Bill nodded and practiced his best funny face. The pair took a deep breath and prepared to crash the party in the most hilarious way possible, hoping their thieving skills would overcome the unexpected challenges of dealing with excited children and suspicious parents. Success would mean a big score, but failure could mean ending up in a very embarrassing video online.
