In the course of testing the HQ's new evacuation system, Private is flung into the koala habitat. When it soon becomes night, the marsupial, Leonard, awakens, terrified of Private since he is one of the zoo's "dangerously psychotic" penguins. After assuring Leonard that he has no intent to hurt him, Private leaves the koala habitat, only to return the next day to find him unconscious. Fearing for him, Private brings the koala back to the HQ, where Kowalski explains that koalas are nocturnal and Leonard himself awakens from his slumber as night approaches. While there, Leonard is accidentally launched from the now-overhauled HQ evacuation system and touches down in Midtown, provoking the penguins to set out to find him and bring him back to the zoo. Soon after locating him, however, their situation becomes more difficult when Leonard falls asleep in the daylight. Eventually, the team manages to get the sleeping Leonard back into the zoo just shy of nightfall, and once night comes, Leonard awakens and spots Marlene and fears her in the same manner he had the penguins, which Skipper chalks up to Marlene apparently having a bad reputation herself.
