This episode gets high marks just for being so fucking insane. It is an idiotic episode, don’t get me wrong, but anything so earnest and high concept — I have to have respect for it. Turns out *all* of Earth’s great societies owe a dept to a certain Froot Loops-colored winged space-serpent called Kukulkan (despite that Kirk insists on calling it KuKLAkan.) Mr. Kukulkan visited ancient Earth and hepped them it his society — but the peoples of the time were very selective in what they decided to keep. Pyramids and ziggurats, mostly. So now, thousands of years later, when Big K. is just kinda getting wind of this, he is naturally annoyed. So he has decided to wipe out humanity. Kirk & co. (aided by an Ensign Walking Bear, someone we’ve never seen before and won’t see again) talk him down from this position. Oh, and there’s a ferocious, electric pussycat. All ends well.
