Sins of Youth part 6 of 12. A de-aged Batman can't let any of his enemies find out what's happened to him, so he asks Tim Drake to don the mask of the Bat, while he dons the Robin costume! It's an ill fit for both as they try to track down the magician Zatanna, who may be able to reverse Klarion's spell. Meanwhile, the Witch Boy pays a visit to the Penguin!
