King Mange is able to Underdog at bay by aiming his Molehole Gun at Polly and making her his prisoner. The Evil monarch leaves with his armies of Mole Men and giant insects to attack the humans on the surface. Underdog uses his heat vision to melt down an overhead stalactite and knock the guard unconscious. Seeing that the people need to prepare for battle, Underdog wants to warn the citizens that the Mole Men are coming. But without any food to give them strength, the situation looks sad. Finally, Underdog realizes that if his Underdog super energy pills can give him super strength, why not give it to the people? Underdog quickly flies to all of the reservoirs in the world and places his super energy pills into the water supply. Polly broadcasts a plea to the people to drink water. They drink the energized waters and fight the Molemen successfully. King Mange regains control of his Molehole Gun and begins to destroy the armies and air forces' weapons. Underdog captures the miserable monarch and ends the war.
