The prince of the Arachnachimps (Spidermonkey’s race), Simion, needs help in retrieving a crystal which is supposedly 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 Simion has been lying, and that the crystal is actually powering an intergalactic communications station. By stealing it, Simion will prevent Earth from calling for help against the upcoming Highbreed invasion. Ben tricks Simion into stealing a box containing a dispenser of worthless DNAlien resin remover acid instead, resulting in Simion having a very unpleasant encounter with the Highbreed commander that employed him.
