Sserpo! Amazing Adventures #6: When a frustrated scientist disposes of an experimental growth formula by tossing it into the ocean it is consumed by a tiny lizard-like creature living on the ocean floor. The missing ingredient for the growth formula was simply water so Sserpo begins to grow. Sserpo is caught by fishermen but by the time they reach port the lizard is large enough to sink the entire island. Nearly 1000 feet tall, the monster heads toward Australia. The Australian Navy diverts the creature with rockets but Sserpo (now 2000 feet high) is headed straight for Japan. Worried that the giant monster will sink their entire country when he first set foot on Japanese soil, the Japanese use an H-Bomb to scare the monster away. As Sserpo continues to grow, scientists fear that he will grow so large that he will upset the orbit of the Earth. Just in time, the inhabitants of Jupiter send a giant skyhook to snag Sserpo and carry him into space.

The alien tells the man that he will be proof that his revolutionary new method of travel works and puts him in a cage while he calls his superiors. Once his superiors arrive and have seen the human, he is to be killed and invasion plans will be drawn up. Suddenly, the Earthman fades away just before the superiors arrive.
