Synopsis:
Aquaman witnesses an alien space ship land in the ocean. He overhears the telepathic communication of the aliens revealing their plans to take over the Earth. Aquaman sends an octopus and a whale to battle the aliens, but their advanced weapons defeat the sea creatures easily.

The aliens then seek out the leader of Earth in order to ask for surrender. Aquaman uses a gold fish to pose as the king. Then using several aquatic tricks, he convinces the aliens that the small fish is very powerful. The aliens break out another weapon, but Aquaman manages to turn it against them. The incident causes the aliens to leave and abandon their plan to conquer Earth.
