As anyone who is familiar with the Pied Piper of Hamelin (Hesperia?) knows, Batman was clearly luring an infestation of deadly rats away from a group of innocents. A storybook scene, indeed.
Ahem. Or, um, he was trying to lure the children into his nearby van. Unclear.
Quickly, Robin, into the Batmobile! And, um, bring your friends while you’re at it!
