The planning van smelled strongly of old pizza and adventure. "Twelve kids," Molly said. "Twelve boxes stacked like a present pyramid. This is perfect." Bill checked his fake mustache in the rearview mirror and adjusted his tie. "What's the security?" Bill asked. "Two dads, one clown, and a very judgmental grandmother?" Molly lowered the binoculars and smiled with professional admiration for the backyard chaos. "The dads are grilling. The grandmother is sleeping. The clown is charging his balloon sword." Bill nodded slowly as if absorbing military intelligence about sausages. "Great. We infiltrate during the cake ceremony. Everyone claps. Everyone photographs. Nobody watches us." Molly pulled two pillowcases from her bag and handed one to Bill with ceremony. "Pillowcases for presents. One holds twenty toys, or one enormous teddy bear with secrets." Outside, children screamed happily while a piƱata wobbled dangerously over their heads. "What is our cover? Are we lost parents, magicians, or very eager party crashers?" Molly produced two laminated badges that read Parent and Assistant Magician respectively. "You are backup magician. I am Aunt Brenda, who lives far away and brings expensive gifts." Bill practiced his mysterious assistant expression and immediately knocked over his juice box. "Magicians never spill juice. Magicians defy gravity, not physics. Also my mustache is falling off." Molly taped the mustache back on with glittery tape stolen from a craft store. "Now you look distinguished. Like a pirate who lost a fight with a formal dinner." The clown began juggling pool noodles painted silver while parents applauded politely and nervously. "That is our signal. When the confetti cannons fire, we move toward the present table." Molly checked her cereal-box watch and gave Bill a serious thumbs up gesture. "Countdown is three minutes. Timmy turns seven today, and he owns far too many toys." Bill tested his pillowcase by stuffing it with empty chip bags for practice. "If we get caught, we claim spontaneous generosity. We were redistributing happiness to our van." Molly nodded and wrote a thank-you note in glitter glue for the present table. "The note says thanks for the donations. We sign it as the Birthday Fairy's Anonymous Benefactors." Confetti exploded over the yard and dozens of children screamed with pure delight. "Go go go. Stay low, stay humble, and do not steal the birthday cake. Yet." Molly slid open the van door and stepped out wearing her finest fake-aunt cardigan. "Follow me. The teddy bear is enormous, but it has wonderful hiding potential for smaller gifts." Bill followed her with his magic wand, which was actually a breadstick in disguise. "My wand smells delicious. If anyone asks, this is a very committed disguise." They crept slowly past the bouncy castle while very distracted parents sang loudly and completely missed their sneaky mission tonight. "Grab the telescope first, then the pony, then the excavation kit, then we run toward freedom and cake." Bill stuffed all the presents into his pillowcase while Molly distracted the grandmother with a long story about sleeping llamas.
