The Crystalites

A meteor crash-lands on Azmot and transforms into a giant crystalline object. Zandor investigates and is attacked by the Crystalites, while Tara and Dorno are captured in crystal cells. Zandor, Gloop, and Gleep steal uniforms, sneak into the fortress and free Dorno and Tara. Gloop and Zok destroy Kryton's ship and he is defeated.
