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.

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.
