Episode 13 – “The Ambergris Element”
A shuttlecraft is sent to the planet Argo containing Kirk and Spock. They are studying a planet that is almost completely underwater, with very small land mass. A strange red marine creature attacks the shuttle and Kirk and Spock are taken captive. When they are found 48 hours later by another landing crew, their lungs have changed and they both can only breathe in water.
Will they be able to be returned to air breathing? Why were they changed? How was this done? These answers and more are answered on this episode.
Nice change of pace seeing an aquatic storyline. The underwater aliens are cool and I like how Kirk and Spock are changed and forced to assimilate the race. Kind of reminds me of what the Borg does in TNG, but in a non-mechanical way. This was a good, entertaining episode. Well written, good voice acting as always and fits the Original Series style well. Recommended.
Episode rating: ⭐️⭐️⭐️⭐️
