(Continuing from previous ask.)
The tapping pauses for a moment when the crew speaks, but than continues. Medium pitch, low, high, low, lower. Repeat.
After a few good minutes, whatever it is other gets bored or decides that the people on the ship aren’t picking up fast enough, Becouse it gives a rapid few taps on the front of the bridge. For a second, what looks to be a very large eye flashes across one of the windows.
(If they have transported down:)
The planet below is mostly water. The small land patches are barren, stone with a few small trees and outcroppings. Giant arches of rocks and stones grow out of the ocean, covered in hanging moss and vines. They look to be natural formations, albeit strange. The water is dark, hard to see through. It looks to have lots of have many cave systems going through it.
[Kirk looks at the patches of land, calculating how difficult it would be to travel from one of them to the other. they're standing on a rather plain portion of land and he wants to explore. Spock scans the water carefully, while Kirk, outside his field of vision, steps on a slippery stone surface in the water, then on another, independent from the first one, and then another one, until he reaches a relatively tall cliff emerging from the ocean. he climbs it (don't ask me how he did it in those high heels). Before Spock looked in his direction again, he was standing on top of it, slightly panting, with his hands lightly scratched. He figured it would be fun to jump in, if the water turns out to be actual water and not some fucked up acid.
Spock turns around, looking for him. They lock eyes. Spock sighs quietly]
Spock: do not move, captain, I shall join you. The water's density is different from Earth's water. It shall be regrettable to see you drown.
Kirk: it's cute that you care. We should look into those caverns over there after we look at this rocky place... [he looked ahead, away from the water. There was fauna Spock will surely love to study. Without any valuable substances or intelligent inhabitants, they likely didnt have anything of use to the Empire. But this was fun. Why not look around a bit?]
[Spock reached the cliff, but just then he stopped dead in his tracks, as if he's heard something. What the hell...? Oh, Kirk could hear it too, now. The same tapping he's heard on the ship. Now he remembered why he was there in the first place...]
