After several comic books are discovered inside a backpack, Skipper warns the other penguins of the dangers of the comic fan lifestyle and of the non-clandestine actions the superheroes contained within them execute and proceeds to dispose of the comics to thwart their negative influences. At night, however, the others secretly view the comics and then decide to act as a superhero team (Private as "Steel Penguin," Kowalski as "The Throbbing Cerebellum," and Rico as "Barf Bag"), foiling minor inconveniences throughout the zoo. When the zoo's clock is accidentally destroyed in the process, Skipper, at the moment unaware that his teammates were to blame, organizes an investigation. While investigating, the group learns of another caped person having been doing thefts around the zoo, which later turns out to be Julien, taking on the role of a villain ("The Masked Booty", his mask on his booty) after finding the disposed comic books himself. Skipper comically fights him as the superhero "Slappy Hurt-Punch" and Julien retires as a villain.
