Molly crouched behind the bouncy castle, peering at the living room window. "Okay, Bill, the plan is simple. We wait for the clown to start the balloon animals, then we slip in through the back door." Bill adjusted his fake mustache, which kept drooping. "And what about the security? I saw a sign that said Beware of Toddlers." "Toddlers aren't security, Bill. They're just small, sticky chaos." "Still, I don't like the look of that kid in the dinosaur hat. He's been staring at me for ten minutes." "Ignore him. Remember, we're the party planners today. Keep smiling." Bill tried a grin that looked more like a grimace. "Shouldn't we have brought better disguises? I'm wearing a balloon hat." "It's festive! Nobody suspects a balloon hat." Molly tugged a glittering gift bag from behind her back. "Besides, I brought an empty bag for the loot." "Molly, that bag says Happy Fifth Birthday, Tyler." She blinked. "Well, Tyler can have a new bag."
