While sailing the Pacific, the Calico crew discover what appears to be a World War II submarine encased in ice, and they summon Godzilla, who frees the old vessel by means of his fiery breath. The crew of the submarine is discovered to be alive and in suspended animation, and after 60 years on ice, they are awakened by the Calico crew. The submarine crewmen incorrectly believe that the war is still going on, causing them to inadvertently release a torpedo, which heads towards the Calico. Godzilla intercepts the torpedo and brings it underwater, but it explodes before he can safely dispose of it, stunning the King of the Monsters in the process. The resulting shock waves disturb a giant octopus, which comes to the surface and grabs the submarine in its tentacles. Godzooky manages to revive Godzilla, who grapples with the octopus and returns it to its underwater cavern, and then sealing it inside with his laser beam vision. Finally, the submarine crew is taken back to civilization
