S2 E3 • Gator Watch

While the penguins are visiting with him in his sewer home, Roger, their alligator friend, states that he hates having to live there, but that he loves being in New York so much that he is willing to endure it. The penguins soon decide to help Roger find a better place to live in the city. They first hide Roger inside a log in a nearby pond, but a lady sees him and screams. They try hiding him as a display in a museum next, but Roger blows his cover by becoming "alive" when a boy pokes him. Following this, the penguins try to hide Roger on a rooftop as a gargoyle, but Roger, afraid of heights, soon falls into a public pool below. Throughout all this, the attempts to relocate Roger make TV news headlines, in a segment called "Gator Watch." While trying next to evade humans, Roger unwittingly enters onto a stage via a building's backdoor and is soon captured by animal control. The penguins then set off after the van transporting Roger to break him out, but they fail to do so before the vehicle arrives at its destination: a well-suited habitat at the Central Park Zoo.

S2 E4 • In The Line Of Doody

In anticipation of the arrival of the zoo commissioner, a security detail quickly examines the zoo and its animals for threats. But as they leave, Skipper believes that the agents have done an inadequate job, so he and the other penguins take it upon themselves to ensure the zoo is safe for the commissioner's arrival to cut the ribbon on a new children's zoo. In doing so, they soon uncover that a pigeon, Frankie, has plotted to "drop one" on the commissioner's suit in retaliation for his implementation of anti-pigeon park regulations. Skipper then tells the other penguins about how he had failed to act under similar circumstances when the previous commissioner had been attacked with bird droppings containing blueberries, vowing to not let the same happen again. The penguins then chase after Frankie, with Skipper flying through the air using a jet-pack, but the pigeon soon ends up releasing his blueberry-infused vendetta. Skipper dives in and takes the hit for the commissioner, and his team is horrified at the resulting look of their leader. Fortunately, however, Skipper reveals that he was wearing a "pigeon-proof vest" as he pulls it off his body. The vest is soon launched at Frankie via a makeshift cannon, resulting in the pigeon suffering the same fate he had intended for the commissioner.

S2 E5 • Can't Touch This

When the penguins hear the scream of a child, they soon learn it was the result of a boy having been bitten by a sheep at the zoo's petting zoo. Appalled by the sheep's attack, the penguins set off at night to retaliate against him. However, the sheep, Randy, soon tells the penguins that he was provoked to bite the boy because the boy had, among other things, beaten on him and had pulled out a clump of his wool. Convinced that they had wrongly judged Randy, the penguins decide to help him out to prevent further abuse by rowdy children. When their attempts at applying a slippery polymer, building up static electricity on Randy's wool, and hypnosis fail, the penguins decide to transport Randy to a farm to live out the rest of his life. Randy is soon taken to a farm by the penguins in a truck, but shortly after his arrival, Randy is horrified at the appearance of the other sheep there, who are sheered and appear to be in a cult-like trance. Consequently, Randy ends up back at the petting zoo, but when the same boy approaches him to attack him again, Randy kicks him away. It is then revealed that Skipper and Rico had taught Randy some of their commando fighting moves.

S2 E6 • Hard Boiled Eggy

While the penguins are engaged in a training exercise, Eggy the duckling enters the HQ, acting in a commando-like fashion. His mother soon locates him there, and tells the penguins that Eggy has been behaving that way ever since their egg-watching adventure. As requested by Eggy's mother, the penguins agree to work with Eggy to convince him that he is not suited to engage in their para-military operations. But when he persists in desiring to become a commando, Skipper leads Eggy to believe that he needs to have a "Penguin Commando License" in order to partake in their operations, and that being able to tackle all the zoo has to offer is requisite for obtaining such. Although briefly successful, this plan soon backfires when Eggy begins to take down all the zoo animals, using the specialized characteristics of each of the penguins that he had learned from them while still in the egg state. Eventually, Julien is the last animal that Eggy had not yet beaten, and thus the only thing standing between him and his "license." But Julien, upon learning that "[his] J.J." (Eggy) wanted to become a penguin, begins dancing to music, and Eggy fails to bring him down as a result. Eggy is then cured of his commando desires but, to the dismay of the penguins, now has taken up Julien's behaviors.

S2 E8 • Fit To Print

The lemurs interrupt the penguins playing computer solitaire in the zoo office in order to sneak a peek at the zoo's new advertising campaign photo, which features the lemurs. After being chastised by the penguins for creating a threat of being seen by humans, Julien points out that the penguins can be seen in the background of the approved ad photo in commando fashion, seemingly unaware that their photo was being taken. Back at their HQ, the penguins decide to set out to digitally remove themselves from the image before it is sent to the ad agency. Whilst attempting to do so at the photographer's house, however, Kowalski inadvertently sends an enlarged version of the incriminating area of the photo to the ad executives. Their situation is made progressively worse when their visit to the ad agency results in the photo being sent to the printer with the caption "Killer Commando Penguins," and then when their attempt to reconfigure the 10,000-copy print job at the print shop instead results in a 1,000,000-copy authorization. When their final attempt to stop the presses results in the foursome being caught up in and inked-up by the machinery, they retreat to the HQ, convinced their covert ops will soon be exposed. However, the new ad which Alice reveals, of penguin body shapes splatted on a white background, keeps their operations secret.
