Season 2

While the Riddler maneuvers Batman into being sued, the Dynamic Duo investigate the supervillain's concurrent scheme.

The Riddler fashions a mold of the face of the unconscious Robin. He contacts Batman with two more riddles. The Riddler tells Batman if he can solve the riddles, he'll know where Robin is. At the same time, Molly dons a Robin costume and a mask. Her task is to trick Batman into taking her to the Batcave. She succeeds but Batman had seen her disguise (but not for the reason most male viewers would guess). Trying to flee Batman, she panics and falls into the Batcave's atomic reactor. Batman rescues the real Robin but the Riddler escapes once more. Batman must solve additional riddles to find the villain's target -- the Moldavian pavilion at the world's fair where an ancient mammoth -- with jewels on the outside and priceless postage stamps inside -- is on display.

The Penguin plots to manipulate Batman into inadvertently devising capers for him.

Bruce Wayne escapes the Penguin's deathtrap and returns to the Batcave. What he doesn't know is that one of the Penguin's clues, an umbrella, has a listening device. As a result, the Penguin listens in as the Dynamic Duo debate what the clues mean and what caper the Penguin may attempt to pull. As a result, the Penguin kidnaps movie star Dawn Robbins.

The Joker decides to fight fire with fire against Batman with a utility belt of his own.

Batman avoids a public unmasking but is unable to bring in the Joker, thanks to the villain's utility belt. Eventually, Batman and Robin are captured by the Joker's gang. But the Joker doesn't know a showdown with the Dynamic Duo awaits.
