The gang happens across the ancient City of Atlantis and they (including Godzilla) end up imprisoned in the city. They soon discover that all the cities residents are under a spell that can only be broken by destroying the giant robot guarding the city.

After their ship is damaged in a storm, the team ends up on an uncharted island. They soon discover the island is inhabited by a cyclops monster. Worst of all, Godzilla cannot reach them because of a force field guarding the island. The team must escape the island and somehow not let the creature escape and threaten the world.

The team discovers the island of the Sirens. The sirens imprison Captain Majors, Quinn, and Brock and put Godzilla to sleep. Pete and Godzuki must find a way to save the others and escape the island before it disappears at sunset for the next 1000 years.
