"Is the clown in position?" Bill asked, lowering his binoculars. "Making balloon animals by the huge bounce house," Molly replied, checking her tactical watch. "Excellent. The distraction is secure. What about the perimeter?" Molly squinted. "The juice boxes are guarded by two grandmas, but the gift table is completely exposed." "How many targets?" he whispered. "Thirty wrapped boxes. Plus a ridiculous shiny envelope." "A gift card. High value. Is the extraction vehicle ready?" "The stolen ice cream truck is idling in the alley." "Perfect. I will crawl under the piƱata. You wait for the sugar rush." "The cake is cut in five minutes. When Timmy blows out the candles, the parents will clap." "And we strike." "Exactly. I grab the Legos, you bag the action figures." "What if a parent asks who we are?" "We are the expensive hired magicians from out of town." "I do not know any magic tricks." "You will make thirty presents disappear into a sack. That counts as an illusion." He frowned deeply. "Good point. Do we wear our ski masks?" "No, face paint. I brought extra washable glitter." "I strongly hate body glitter." Molly sighed. "Deal with it, Bill. Let us steal some toys."
