| Synopsis | Once a year, in conjunction with the "Inventor's Club," the Blackhawks test out new inventions that may lend themselves to industrial use, such as the Flying Buzz-Saw, or the Mechanical Caterpillar, or the Radio Man, a giant robot. Hearing reports of strange goings on, a group of reporters discover the testing. Shortly after, the machines are stolen by Baron Kram and his henchmen, who proceed to test the machines in their own way. |

| Synopsis | The Blackhawks track Dr. Vokar and his henchmen Hack and Frisco to a Carribean Island. But the three flee into the stormy ocean rather than be captured. When they're shipwrecked on a deserted island, they find that eating the fruit grown there causes them to grow into giants, which the Blackhawks discover when they follow them there. |
