Molly crouched behind the hedge, peering at the bouncy castle where shrieking kids bounced like hyperactive popcorn. Bill slouched beside her, adjusting his cartoonishly oversized clown nose with a sigh. “We wait until they sing Happy Birthday,” Molly whispered, eyes gleaming. “That’s when the sugar rush hits peak chaos.” Bill snorted. “You want us to rob a children’s party? These tiny humans have better security than Fort Knox. One wrong move and we’ll be buried under an avalanche of juice boxes.” “Relax, it’s foolproof. I’ll distract with the magic trick kit while you stuff the goodie bags into the sack. Nobody suspects the guy in the mascot costume.” “Last time I wore the bear suit I got hugged by a toddler with sticky fingers. Never again.” Bill adjusted his fake mustache. “Fine. But if we get recognized, I’m blaming your terrible balloon animal skills.” Molly grinned, checking her watch. “Thirty seconds to showtime. Try not to cry when we steal their favorite toys.” “Speak for yourself,” Bill muttered, pulling the zipper on his duffel bag. “I’m not the one who cried during Pin the Tail on the Donkey last week.”
