Bill crouched behind the minivan holding stolen party invitations tightly. "We need a plan that does not involve crying children." Molly wore a fake mustache and oversized birthday clown shoes. "Children always cry, Molly, especially when presents suddenly disappear fast." The community center buzzed with screaming children eating sugary cake. "We dress as clowns, walk in, grab everything, leave quietly." A mountain of bright presents glittered temptingly through the window. "I look ridiculous in red noses and squeaky oversized shoes." Bill studied the hand drawn map with intense criminal focus. "You look ridiculous always, so wear the nose with pride." Molly chewed bubble gum while polishing her toy water pistol. "Fine, but I refuse to sing happy birthday for cover." The door squeaked open whenever parents carried juice boxes inside. "You will sing, dance, juggle, and distract screaming sugar monsters." Bill pointed toward the clown entrance with a trembling finger. "While you perform, I will stuff presents into giant sacks." Molly giggled loudly despite the seriousness of their terrible mission. "What if some kid recognizes us from last disastrous Halloween?" A security guard shaped like a grandpa snored near balloons. "Nobody remembers Halloween, Bill, trust me, we were invisible ghosts." Bill whispered the getaway route involving tricycles and a van. "Great, so I am Buttons the extremely unhappy birthday clown?" Molly nodded solemnly while stealing icing from an abandoned plate. "Yes, and I am Sparkles, your cheerful criminal clown sister." Inside, a magician botched card tricks to polite toddler applause. "Do we steal from a six year old named Timmy?" Bill checked his watch twice because sugar crashes create chaos. "Especially from Timmy, he gets way too many Lego sets." Molly pulled two gift sacks from her polka dot backpack. "Security looks tough, Molly, that grandpa has sharp suspicious eyes." The wind carried the smell of popcorn, frosting, and regret. "Relax, I packed extra cupcakes for bribing grumpy security guards." Bill practiced his cheerful birthday voice with horrifying results daily. "Brilliant, sugar bribery always beats our terrible lock picking skills." Molly slapped glitter onto his cheeks with excessive sisterly enthusiasm. "After cake time, lights dim, then we unleash confetti chaos." A line of minivans blocked their escape alley almost completely. "I grab the action figures, you take dolls and puzzles?" Bill swallowed hard staring at the towering bouncy castle obstacle. "Deal, but I want that noisy drum set for revenge." Molly mapped confetti cannons, cake tables, and crying toddler zones. "No drums, Bill, remember the last noisy getaway car disaster?" Their previous library heist ended with paper cuts and shame. "Fine, no drums, but I get the chocolate fountain afterward." Bill remembered jail cells smelled better than sour milk costumes. "Focus, we enter through kitchen, exit past bouncy castle quickly." Molly licked frosting thoughtfully while considering grand larceny versus mischief. "What about Timmy's mother with the terrifying laser pointer eyes?" Both thieves fist bumped beneath the flickering parking lot light. "Smile, offer balloons, steal presents, run like really hyper toddlers."
