Aqualand was actually "Marineland of the Pacific":  

"Tell Trump to Send ICE to Iran".  Not a bad idea Rachel.

Two mistakes mar an otherwise pretty good episode.

When one of the bad guys stumbles back into a knife and dies, the next shot zooms onto the blade.... which is miraculous clean, with no blood at all.

Mannering asks Nikki to hold a flashlight while he works on something. She takes the obviously unlight flashlight & points it at his work, another camera view shortly after shows us the lens of the flashlight, very obviously NOT on. 

From archived tv.com:  The plot of the episode bears a striking resemblance to the 1967 Star Trek episode Arena. In both cases, a space battle is interrupted by an omnipotent power, the captains are given primitive weapons and forced to fight hand-to-hand on the surface of a planet while the crew watch and the hero spares the villain at the end.
