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.

After his recent release from jail, The Penguin has started his own protective agency and is thwarting small time hoodlums everywhere he goes. Batman & Robin decide to send in an undercover Alfred to spy on the newly reformed Penguin and his recently acquainted high society friends. However, the Penguin has anticipated Batman and Robin's every move and manages to give them a makeover into wanted men instead of him.

Already wanted for a robbery they didn't commit, Batman and Robin fake their own deaths with a little help from Commissioner Gordon and Chief O'Hara. They even allow the Penguin to take hold of the Batmobile, now renamed 'Birdmobile' in order to keep track on them via a hidden camera.

Alfred is kidnapped by the Penguin ans his finny fiends while buying caviar for the Multimillionaires Annual Award Dinner. Although the loyal butler does not know the secret location where the dinner is to be held, Penguin brainwashes the man-servant as part of his diabolical scheme. Batman and Robin track down the Penguin's hideout on a fishing pier owned by 'Knott A. Fish', only to walk into a trap.

The Penguin learns the location of the Multi-millionaires Annual Award Dinner from Alfred: on board Bruce Wayne's S.S. Gotham Neptune. His female fink Finella replaces the beauty queen for the chosen charity Miss Natural Resources, pops out of a giant cake at the diner and proceeds to gas all the multimillionaires present, as well as Bruce Wayne and Master Grayson's replacements: Batman and Robin.

The Penguin appears to have gone straight. (Evidently the citizens of Gotham City have short memories; he tried the same trick in season one.) Not only that, he has emerged as the leading contender for mayor of Gotham City, thanks to a little-known provision of the city charter that permits felons to run for elective office. Mayor Linseed, facing almost certain defeat, convinces Batman to run for mayor. This displeases the Penguin, who doesn't want to leave anything to chance. He lures Batman and Robin into a trap and, by episode's end, things don't look good for the Dynamic Duo.

After escaping the Penguin's death trap, Batman still faces an uphill run to defeat the Penguin in the race for mayor of Gotham City. The Feathered Fiend uses every dirty trick he can think of to ruin Batman's reputation. But the Penguin discovers opinion polls aren't what they are cracked up to be. Still, Batman and Robin will need to subdue the villain before his plot can be put down once and for all.

Penguin has opened a fancy restaurant called The Penguin's Nest. There every order has to be written down by the customers on a piece of paper. He then plans to get himself arrested and hand over the handwritten notes to a forger doing time by the name of Ballpoint Baxter. Suspecting a scheme, Batman urges the police not to send The Penguin back to his permanent cell. Unable to reach Ballpoint, The Penguin and his culinary cohorts escape from jail, taking Chief O'Hara along as a hostage.

Attempting to save Chief O'Hara from drowning inside a metal trunk, Batman and Robin find themselves under fire from the Penguin's henchmen. Batman instructs Alfred to pose as famous forger Quill-Pen Quertch (complete with false fingerprints), but the Penguin recognizes Alfred as soon as he puts on his glasses. The evil Bird-man and his cronies then visit stately Wayne manor brandishing a giant Butler-pie.

The Joker and the Penguin team up on a crime wave based on signs of the zodiac. The pair, aided and abetted by a woman known as Venus, keep Batman and Robin on the run. The Dynamic Duo manage to capture the Penguin but the Joker remains on the loose. Batman and Robin figure the Joker's next caper will take place at a museum and lay a trap. But the heroes are captured instead. Now, Batman and Robin face almost certain death; the heroes are to be crushed beneath a giant asteroid on display at the museum.

Batman, summoning all the strength he can muster, breaks his chains and frees Robin from the giant clam. The heroes arrange for the Joker's former confederate, Venus, to stay at an apartment while they figure out what to do next. Meanwhile, the Joker has freed the Penguin from Gotham State Prison to continue their crime wave. The Joker tricks Venus into asking Batman to take her to the Batcave. The Dynamic Duo take her to their base of operations (but only after making her fall asleep first). When they arrive, the Joker, Penguin and assorted thugs are revealed to be hiding in the Batmobile's trunk. Batman, however, anticipated this and none of the criminals know where the Batcave is. A figure erupts, with Batman and Robin finally ending the zodiac crimes.

As a front for his next crime wave, the Penguin forms a motion picture company. He teams up with Marsha, Queen of Diamonds, and gets Batman and Robin to take part in his movie. Marsha attempts to put Batman under her spell with drugged lipstick during the love scene, and filming at the Gotham City Museum of Antiquities turns out to be a good cover for the Penguin to snatch some ancient armor. Moreover, when the fight scene turns out to be all too real, the Dynamic Duo are captured and tied to a giant catapult about to be sprung.

In order to keep a close eye on the Penguin (and hopefully locate the stolen chain mail armor), Batman and Robin rejoin Penguin's movie efforts. The next part of his film is to take place in medieval times. Therefore, Penguin has the Dynamic Duo dress in armor suits, but only to trap them with a giant magnet while he snatches top-secret papers from the Hexagon. Batman and Robin free themselves and follow the villain, but after a losing battle with him, the Penguin has them hauled off as scrap metal to be crushed.

Batman and Robin get back on the Penguin and Marsha, Queen of Diamonds', trail. Several escaped lizards lead them to the villains' hideout, where they find the stolen chain mail suits. Remembering an earlier clue from the Penguin, they head to the federal subtreasury to find that the Penguin, Marsha, and their cronies have broken into a vault containing ten million dollars in gold bullion. The Dynamic Duo shut the vault door on the criminals and try to prepare for every breakout scenario, but the Penguin has a daring plan of escape that no one could have counted on.

"Enter Batgirl, Exit Penguin", is the first episode of Season 3 of the Batman television series', first aired on ABC September 14, 1967 as its ninety-fifth episode. It guest starred Burgess Meredith as The Penguin, and also was the first appearance of Yvonne Craig as Police Commissioner Gordon's daughter, Barbara Gordon, a.k.a. Batgirl.

Lorelei Circe, aka The Siren, launches a two part plan to become the richest and wickedest woman in Gotham City. First she puts Commissioner Gordon under her stunning spell and orders him to stow away in the Batmobile in order to find out the location of the Batcave as well as Batman & Robins secret identities. Secondly she entrances millionaire playboy Bruce Wayne and implores him to sign over all his wealth and belongings to her.

The Penguin teams up with parasol collector Lola Lasagne. Together, they plan to rig the upcoming Bruce Wayne Handicap to make a fortune from Lola's prize racehorse Parasol. They break into Glu Gluten's Glue Factory to steal a condemned horse, planning to switch horses before the race and make their money by betting on the real Parasol. When Batman, Robin, and Batgirl catch up with them at the glue factory, Penguin sneaks outside and plasters the Batmobile with a sticky glue.

The Penguin steals a priceless folio of famous parasols from the Gotham City Library. He plans to wager the $10,000 earned from its ransom on a rigged horse race. Aided by his partner-in-crime Lola Lasagne, he disguises the favored entry Parasol as the unknown "Bumbershoot," then enters a painted glue factory horse as "Parasol". With everyone betting their money on the fake horse, it looks like the Penguin will make a fortune when the real Parasol wins the race. But he wasn't counting on a last-minute entry of Bruce Wayne's, the horse Waynebow, ridden by none other than Batgirl.

Nora Clavicle, a women's rights activist, uses her influence to have Commissioner Gordon, Chief O'Hara, and the whole police force fired and replaced with women. She cuts ties with Batman and Robin, then launches her plan to blow up Gotham City with explosive-packed mice and collect on the insurance. The Terrific Trio look for a way to neutralize her mechanical hordes before it's too late.

The Penguin taints the ink at the U.S. Mint with Lygerian Sleeping Sickness. As word of the infected money gets out, citizens of Gotham City empty their cash right onto the streets - and into Penguin's pockets. But when Bruce Wayne spreads word of the infected bills worldwide, the Penguin realizes his ill-gotten gain is worthless and threatens a more devilish plot if the warning is not retracted.
