"Molly, the party guards are just toddlers." "Bill, toddlers have the best security clearance: snack crumbs." "Quiet. Listen—what’s that?" "The cupcake cannon. It goes off when someone yells 'Happy Birthday!'" "Perfect. We strike during the chorus." "I brought a decoy gift bag: it’s full of glittery socks." "Glitter? That’s basically a tracking beacon." "Only for us. The parents will slip, admire the mess, and forget to count." "Do we have the entrance code?" "Yes: 'We’re here for the science show!'" "And if they ask our names?" "We'll say 'Captain Present' and 'Doctor Wrapper.' Sounds official." "Where’s the real stash?" "Under the table, between the cake and the suspiciously fancy wagon." "Any alarms?" "Nope. The only siren is a bubble machine." "Then we use bubbles as camouflage." "Exactly. You pick the loudest present." "Because it’s heavier?" "Because it makes the kid squeal, and the squeal draws eyes away from our hands." "Okay. When do we leave?" "After the piñata. Everyone’s busy hugging sugar violence." "Bill?" "Yeah?" "Steal the tiny pony?" "Steal it. But we must return the horsey bubble bath." "Morals!" "Morals." "Take the big box; I’ll handle wrap speedruns." "Deal—undercover gift mimes. If questioned, we perform interpretive ribbon!" "Very quietly."
