S3·E8 The Big Dipper, Part 4

Simon has finally forced the people of the city and the world to give him ultimate power. Underdog is still stuck in the polluted mud of what was once the Atlantic Ocean. He swallows a super energy pill from his ring and, regaining his super powers, he flies back to the city and tricks the two villains into giving him all of Simon's jars of water. In retaliation, Simon prepares to destroy the Big Dipper with his pistol. Our hero takes the gun away from Simon and knocks the two villains out. Underdog refills the world's entire waterway, saving the world once again.
