Trapped inside of the Giant Clam, it looks like the end of Underdog and his friends. Polly remembers to give Underdog his super energy pill, and he tickles the clam into helpless laughter. The trio to escape, but not unnoticed. The Empress has had enough of Underdog's interference and sends her guards to trap the trio inside an inescapable bubble. The guards shoot their bubble-guns, trapping Underdog and his friends inside a bubble-like cage. Polly hands over her hairpin to our hero, and he pops the bubbles, sending the guards running off in fright. Underdog then heads for the gates of Maldamere, where he bests the giant octopus, destroys the tidal wave making machine and forces The Empress and The Emperor to give up their plans for conquering the surface world. Having achieved victory, Underdog returns Polly and Professor Moby Ahab to their ship.
