King Klobber, the King of Zot, consoles his daughter, the Princess Glissando. To find a suitable beau, he puts all of Zot's top men in a ring to battle it out for the Princess's hand. The winner is Semore, who the Princess looks at in disgust and zots (punches) him. The King calls on his prime minister, Goggle, to search for a suitable mate. He locates Underdog and is sent to bring him back.
