Molly crouched behind the minivan across from the bright house, binoculars glued to her face. "Okay, that's twenty kids, one clown, and a mountain of presents by the cake table." Bill scribbled furiously in a tiny notebook, dressed in a too-tight clown suit. "Why am I the clown again? Last time the wig gave me a rash for a week." Molly lowered the binoculars and grinned at him. "Because you scream trustworthy birthday entertainment, and I scream suspicious aunt." Bill tugged at the rainbow wig, wincing as a balloon animal squeaked in his pocket. "I look like a traffic accident at a circus. The kids will cry before I even steal anything." Molly patted his shoulder with fake sympathy. "Perfect. Crying kids means distracted parents. Distracted parents mean present time for us." "Remind me why we are robbing a six-year-old? We used to do banks, Molly. Banks!" She pulled out a crumpled invitation covered in glitter and crayon. "Banks have cameras and vaults. Timmy Higgins has a bouncy castle and zero security awareness." "He is six. His security team is his mom with a juice box." Bill peeked over the minivan as music and screaming drifted across the street. "Okay, what is the plan? I walk in honking and you grab the loot?" "Exactly. You do your terrible magic show, pull a rabbit, cause chaos. I pose as Party Mom." She held up a stained apron that read Kiss the Cookout Queen. "You do not look like a Party Mom. You look like you sell fake Rolexes behind a gas station." "Rude but fair. Still, I have snacks. Moms with fruit snacks are invisible. It is science." Bill sighed and pulled a deflated giraffe from his sleeve. "Fine. I distract, you stuff presents into the diaper bag. Then we meet at the getaway car?" "No getaway car. We are escaping on the bouncy castle. Deflate it, roll it, run." Bill stared at her, mouth open under the red foam nose. "You want to steal a bouncy castle too? That thing is twenty feet tall, Molly!" "Go big or go home. We can sell it. Think of the resale value for angry divorced dads." A chorus of Happy Birthday erupted from the backyard, off-key and loud. "That is our cue. Remember, blend in, smile, and never accept a juice box. It is a trap." "What about the clown they hired? The real one? He will know I am a fraud immediately." Molly smiled sweetly and dangled a pair of tiny handcuffs made for party games. "Do not worry. I already paid him fifty bucks to call in sick with glitter lung." "You are brilliant. Terrible, but brilliant. Let us go steal from toddlers like real professionals." They bumped fists and waddled toward the screaming party. "Remember code red means run, code yellow means cake, and code brown means diaper emergency, obviously." "Got it. If anyone asks, my clown name is Sparkles von Stealyourstuff." "Perfect. Now honk twice and look totally innocent."
