Neither the goblin nor the club is doing much of anything at present.

...the club was probably magical, right? Maybe? Can he use that against the wall?

Earlier on it did go through some small trees like they were a small-tree-size quantity of butter. It doesn't take many strokes to crumble a stone spike.

There's another roar from below, and the stalagmites start gnashing up and down again, but this time he doesn't have to hang on. It just means he's aiming at a moving target.

Smashity smash smash! He can aim, and he doesn't need to hit the same spot all the time, really, he just needs to do away with the structural integrity of the place.

This creates clouds of dust, and the occasional falling rock when a piece gets jarred loose at the top, and most importantly a hole.

The roar grows higher-pitched. It's the equivalent of a shriek from something much too big to recognizably shriek.

Yeah whatever, club backpack corpse lunge through—

Still a moving target— he hits it, and worms through in a cloud of gravel.

Cloud of gravel! Woo!

He turns around to look at whatever it was.

It was a ring of stones. Closer together than the one he stepped into, but otherwise the same. Rocks arranged in a circle.

...he throws a rock into it.

Nothing happens.

He gets a stick and scatters all the rocks.

They scatter like rocks should, just like the last circle.

He starts searching the goblin (ew ew ew ew ew) for anything useful or valuable or magical.

The goblin, when he finds the body, is significantly less ew than might be expected. It's a fossilized skeleton.

—fine, he'll think about the obvious implications later. Now he'll search the not-ew body for anything of use.

Nah. It’s just a stone skeleton, incomplete and deteriorated enough that it could almost pass for a regular hominid. There’s nothing to find.

Hm. Alright.

Club in hand, backpack on back, he steps into where the circle used to be.

The spikes reappear from the former sites of the rocks he scattered. Stalagmites, weird dome made of parallel vertical lines, outside world going flat. It happens faster this time, and bars him back in.

He swings the club left and right lazily. "How would you like it if I just, you know, hit you with this until your teeth were dust?"

It doesn't speak a reply, what with not having anything even analogous to a tongue. The response is more along the lines of the walls shooting upward or the ground dropping away under him, depending on point of view.

"Aack!" He can try to stay near the ground. "I'll take that as a no," he says, attempting to steady himself. "But I have an alternative proposition."

It goes still. Now that the walls are done shooting upward he's at the bottom of a pit with light coming in between the spikes at the top, but it's no longer getting deeper.

"See, I have nothing against you eating random animals or things that are already about to kill or maim other people. I have a thing against you eating people who were just, you know, not doing that. So I'd like to propose a deal."

It continues the not being capable of speech, but doesn't resume trying to eat him.
