Did You Know?


First occasion where Spock receives a mind touch from "another" Vulcan. In order of size, Spock II is the second largest to meld with. (Unless the Lactrans from Star Trek: The Animated Series: The Eye of the Beholder (1974) are equal or bigger.) The cosmic cloud from Star Trek: The Animated Series: One of Our Planets Is Missing (1973) is first. See more »


Spock 2 - a giant like Stavos Keniclius 5 - is introduced wearing his Starfleet Federation uniform. Though Spock himself has been cloned and gigantified, his clothes could not have been. They would have to be manufactured - including his giant comm badge and his boots - and there would be no need to go to all this trouble. (And where would one get boot leather on an all-plant planet?) See more »

Just Make It Up As You Go
18 March 2017 | by HitchcocSee all my reviews

This animated series seems to be getting worse as it goes along. The guys go to a planet that is inhabited by plants that move around. Sulu picks up a plant with his bare hands (a little stupid considering it's an alien planet). He would be killed except the walking, talking plants save him. Then we find out the place is being run by some big human who is the fifth clone of some other guy. He has some plans for the master race and kidnaps Spock using dragons with corkscrews. Then McCoy creates a plant spray and..... I can't even try to explain what happens. This has got to be about as ridiculous as one can get. I know this was Saturday morning stuff, but it pretends to have an intelligent basis. It's as if some writers were in a room with about an hour to put together a plot and they turned in the first draft.
