the Dark Planet

plot
Professor Haggerty discovers that a Uranian plant he has been studying can move and speak on an ultrasonic level.  However, he believes that the plant is quite young as it has not yet learned to speak its native language.  Raeburn sends Dart and his crew to Uranus get a recording of the plants’ language.  When they arrive, one of the plants attempts to strangle Slim.  Dart and Husky try to rescue him, but are held back by more of the plants.  While Dart returns to the Galasphere to get the laser gun, Husky manages to fight off the plants and rescues Slim.  As they hurry back to the Galasphere, they narrowly avoid being caught by the Uranians.  However, they succeed in obtaining the recording.

notes
The Uranian plants would later appear in the episodes the Invisible Invasion (in which they would first be referred to as Duos) and the Jitter Waves.
