The Enterprise travels to the planet Janus 6 to assist the mining colony there. Kirk, Spock and McCoy beam down to the planet where Chief Engineer Vanderberg tells of a creature loose in the mine tunnels killing some of his men. The monster seems to appear out nowhere then disappears just as quickly. Finding that the creature, known as a Horta, lives in a newly opened part of the underground mining complex, Spock uses the Vulcan mind meld to determine why it is killing the miners. Written by
Did You Know?
The clubs used by some of the Janus VI colonists during their hunt for the Horta appear to be of the same design used by Kirk during his fight with Spock in the transporter room in Star Trek: This Side of Paradise
(1967). See more
After Spock's initial mind-meld with the Horta, Kirk and Spock discuss asking the Horta where the 'Retardation mechanism' (for the main reactor) is. There is never any indication that they knew the mechanism was cut out and not simply dissolved away by the Horta. Nor is there any logical reason why the Horta would keep and not just destroy the reactor pump, if it wished to drive them off the planet. See more
