The four criminals equip themselves with a dehydrator that can turn humans into dust (an invention of Schmidlapp, who is unaware that he has been kidnapped), escape in a war-surplus, pre-atomic submarine made to resemble a penguin, and recruit three pirate-themed henchmen (Bluebeard, Morgan and Quetch). Batman and Robin learn that the yacht was really a holographic projection and return via Batboat to a buoy concealing a projector, where they are trapped on the buoy by a magnet and targeted by torpedoes. They use a radio-detonator to destroy two of the missiles, and a porpoise sacrifices itself to intercept the last one. Catwoman, disguised as Soviet journalist "Kitayna Ireyna Tatanya Kerenska Alisoff" (acronymed as Kitka), helps the group kidnap Bruce Wayne and pretends to be kidnapped with him, as part of a plot to lure Batman and finish him off with another of Penguin's explosive animals (not knowing that Bruce Wayne is Batman's alter-ego). After Bruce Wayne fights his way out of captivity, he again disguises himself as Batman, and the Dynamic Duo returns to the United Underworld's HQ, only to find a smoking bomb. Batman is met with frustration rushing all over the docks in hopes of locating a safe place to dispose of the bomb but does so in the nick of time. The Penguin disguises himself as the Commodore and schemes his way into the Batcave along with five dehydrated henchmen. This plan fails when the henchmen unexpectedly disappear into antimatter once struck: the Penguin mistakenly rehydrated them with toxic heavy water used to recharge the Batcave's atomic pile, leaving them highly unstable.
