Episode Title:
It's About Time.
Episode Description:
After creating a time machine called the "Chronotron," Kowalski is in need of one final chemical before he can fire it up for time travel. However, when he and the other penguins are out to obtain it, Kowalski's future self appears to Private and instructs him to not allow his present self to complete the Chronotron, lest great chaos in the future result. Later, as Private has no success in foiling the Chronotron, another future Kowalski appears to Skipper to ensure that his future self instead build the Chronotron. Eventually, the three Kowalskis see each other, creating a black hole in space-time. Two Kowalskis use the Chronotron to travel back in time, thus becoming those who had appeared to Skipper and Private. The space-time hole is then shut when Rico throws the Chronotron into it.
