The next phase of their plan is to get the Granite Gun which is in the throne room of Captain Marblehead who is enjoying his meal . Polly attempts to clobber the Captain with a pipe, but it has no effect on his stone head. He then calls for the guards who round up the prisoners. In the confusion, the guards hurl a projectile at the prisoners who duck and allows it to break open a wall to reveal a phone booth. Shoeshine sees this opportunity and changes into Underdog. He races to free the prisoners only to face Captain Marblehead and the Granite Gun . Underdog gets temporarily made of stone but then breaks free. He then melts the Granite Gun with his x-ray vision.
