Well, it did give us whatever this is supposed to be.
I also like tribbles... the fact that they just made (or purchased) throw pillows and overdubbed purring on to them is pretty hilarious. McCoy talks about observing their anatomical structure at one point, but let's be real, it's probably just goose down.
Some of the medical devices McCoy uses were salt shakers painted if I remember correctly. Then thereâ€™s that one same shot of the ship orbiting a world, with the planets sometimes airbrushed different colors for different episodes. And how about those cheap space suits or environmental suits they sometimes wore that looked like they were made of cheap plastic rain poncho material
