The team and Godzilla are, strangely, teleported back to prehistoric times. They must find their way back to the present time without disrupting the past.

While on their way to visit an oil rig, the team is captured by a mad scientist who has the knowledge to clone people. He plans to make a copy of the crew and use them to steal the oil and make a fortune. The team has to escape and alert Godzilla.

While helping the crew out of a hurricane, Godzilla wanders through a mysterious pink fog. Before long, the strange fog causes Godzilla to start shrinking. Even worse, a fly also inhaled the gas and is now growing to gigantic proportions and seems to be targeting Godzooky and Brock. The others must find a way to get Godzilla and the fly back to their normal sizes.
