His final target is none other than Batman, who provided the key testimony in the Mad Hatter's trial. Batman and Robin have the Mad Hatter and his gang cornered but the criminal mastermind manages to encase the Caped Crusader in plaster of Paris.

If he picks the wrong one, he'll face certain doom. The hero makes the wrong selection and is about to be attacked by a tiger.

Batman evades the attacking tiger thanks to his utility belt. First, he scales the wall. Then, he uses a sonic device "to split the tiger's skull," as narrator William Dozier informs us.

The Joker launches a new crime wave with robberies that appear to make no sense, such as stealing hairpins from rich women and a hole from a golf course. But the Joker knows exactly what he's doing. Batman and Robin are in pursuit and eventually invade the villain's headquarters. The heroes are placed in a chamber and are told if they can float for an hour, they'll go free. The Joker then begins to flood the chamber with poison gas. The Joker says the Dynamic Duo may not be able to swim in the gas "but you can drown in it!"

At each of these events, the villains are accompanied by German film maker Van Bloheim who captures everything on celluloid.
