Molly leans against a fence, twirling a piñata stick. "Nailed it. The clown’s got a *fanny pack* of goodie bags stuffed with glow sticks and lollipops that’ll make a 4-year-old sob if we take ’em." Bill squints at the bounce house, where a toddler’s unicorn bounce deflates with a whimper. "Party’s at 3. Clown’s doing a magic trick—probably the *worst* magic trick ever. Bet he’ll drop the wand, fake a gasp, then pull out a balloon. Classic." Molly snorts. "We hit the present table first. The dinosaur one’s leather-bound coloring books. Saw the mom place it by the cookie stand—she’s chugging lemonade, too busy to notice we swap it with a grocery bag of *rice cakes*." Bill nods, eyes darting to the sprinkler. "What if the princess dress kid cries? Leave before the cake. Sprinkles stick—we’ll look like a snowman. Clown said kids are *too hyper* and he’s ‘going home to watch paint dry.’ Ahimsa, right? Let’s make his day. Steal presents, swap with rice cakes—by 4, we’re at my place eating gummy bears while the bounce house deflates." Bill sighs, grinning. "Fine. But if a toddler gives the ‘scared cat’ look, we bail. Don’t jail over stickers." Molly tosses him a glow stick. "Deal. Glow sticks make us look like we’re *winning* at life. Kids won’t notice… until the rice cakes run out." She grins, nudging him. "C’mon—Bernie’s already eyeing the exit. Let’s make the *toddlers* the real heist victims." Bill rolls his eyes, but follows, already tugging on gloves. "Hurry. I don’t wanna explain why I’m holding a toy train to the party."
