Molly and Bill planned in whispers. "Bill, we need to plan this children's party heist carefully to steal all the presents without any trouble. How do we get in without raising suspicion?" said Molly. "We pose as the hired clown and face painter Molly. I keep the kids laughing with my act while you swipe every present off the table and into our sack. We wait for the happy birthday song as our signal then run like hell to the van. No cake though that would be wrong," said Bill. "Agreed. The cake stays but everything else is fair game. During the piƱata bust is even better for cover with all the blindfolded swinging and yelling. If any kid asks we say it's a magic trick and the presents are flying to toy heaven or something funny like that. This will be our most ridiculous heist ever but I think it will work if we stick to the plan," said Molly. "You are brilliant. Those little brats won't miss anything for long and we'll be laughing all the way to the black market with dolls and trains. Let's review the exit one last time so we don't trip over any toys on the way out."
