The Penguins of Madagascar Season 2 Episode 59 I Know Why the Caged Bird Goes Insane Episode Title:I Know Why the Caged Bird Goes Insane.Episode Description:Kowalski is ecstatic to learn that the Invexpo science convention has come to Central Park, only to be unable to attend after accidentally pulling a billboard down on himself, which fractures his legs and confines him to the nursery for a 30-day recovery. To liven Kowalski's spirits, Private suggests that he, Skipper, and Rico attend Invexpo instead; Skipper reluctantly agrees, finding the event surprisingly fun. Meanwhile, Kowalski's sanity quickly deteriorates from the boredom of confinement and the inability to attend Invexpo himself. But later, when he notices a space squid landing and the rest of the team unaware, he gets Marlene's attention to assist. After it takes Kowalski's Extend-o-Grab invention because of the hand–finger capabilities space squids lack, the creature returns to the sky after Marlene uses the invention to poke at the invader. Afterward, Kowalski no longer feels upset about not attending Invexpo, as he had "already witnessed the greatest invention this world has to offer"—his own.
