When they realize their operation is at risk of being exposed the penguins head to an ad agency to destroy the incriminating evidence.
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. They get forced to self-destruct their HQ/habitat and cancel the penguin credo. However, the new ad which Alice reveals is only body shapes of the penguins, splatted on a white background, which secures the penguins' cover and recommences the penguin credo. Unfortunately at the very end, their HQ/habitat still self-destructs.
