The Organ Grinder drove the train while fellow prominent gang members like the Snake Woman and Sword Swallower put the boys in animal cages. Later in the evening Batman intercepted the train after learning of the plan at the Maxquerade Ball. After striking a pose on top of the train during a lighting flash, Batman proceeded to further intimidate and interrogate the Organ Grinder. After taking care of the situation, Batman gave a handwritten note with his insignia to the circus monkey to deliver to the Penguin. The police were likely alerted to the captured thugs and the train seized.
