Episode 23

The prince of the arachna-chimps, Simian, needs help in retrieving a crystal which is the symbol of the monarchy on his planet. The crystal is being kept in a base on the moon. Ben offers his help, but Kevin and Gwen are skeptical. In the midst of the battle, Ben discovers that Simian has been lying, and that the crystal is actually powering an intergalactic communications station. By stealing, it, Simian will prevent Earth from calling for help against the Highbreed invasion. Ben tricks Simian into stealing a worthless acid dispenser instead, resulting in Simian having a very unpleasant encounter with the Highbreed that employed him.
