 Baron Greenback uses the minimizing peaka ray to shrink himself and his cronies and use the equally shrunken Frogs Head Flyer to enter the body of Colonel K. at the secret, secret service H.Q. Taking control of the Colonel s voice box, the villainous Toad relieves Dangermouse and Penfold from their duties. However, Professor Heinrich Von Squwawkencluck figures out the Baron s plan and shrinks DM and Penfold so they can enter the Colonel s nose, traveling in a conveniently shrunken Spacehopper.
