Molly spread a crayon map across the bakery table, pinning one corner with a jelly doughnut and another with Bill's elbow. The map showed Mrs. Puddlington's garden, the bouncy castle, the magician's suspiciously large hat, and a mountain labeled PRESENTS in purple glitter. Bill wore a cardboard crown for camouflage, though it kept sliding over one eye. Molly had chosen a unicorn sweater, reasoning that no adult questioned unicorns near cake. "We enter during musical chairs, grab gifts, then vanish behind cupcakes," Molly whispered. Bill nodded gravely, accidentally honking a party horn tucked in his pocket. Every pigeon on the windowsill judged him. Their getaway wagon waited outside, painted with flames and one apologetic daisy. It had a top speed of brisk toddler, unless pushed downhill. "Or we bring decoy presents, swap labels, and leave confusion," Bill said. Molly considered this, licking frosting from her thumb like a mastermind sampling evidence. The plan was terrible, rude, and likely to end with them face-painted as kittens by an aggressive aunt. Still, the glittering pile called to them. Bill saluted with a doughnut. Molly folded the map, leaving jam on the trampoline. Tomorrow, they would become legends, or babysitters by lunchtime, unfortunately.
