Anything cool you can do with Antlion cave-in boulders?

[Faintly Macabre]

Pretty much what it says on the tin. Make some indestructible pens or any of that kind of stuff creative people come up with?

Security doors. Mobs can't pass through rows of boulders, but think that they can.
Particularly useful against Depths Worms waves. Can be used against Shadow Splumonkeys, too.

You can move them to the surface and create enclosures that can't be broken by vargs/hounds (telelocate a varg in there for gem farming).

They're also quite pretty when paired with glass spikes / glass castles.

I use it decorating garden or just use fence for cave worms!

[Rellimarual]

Very useful indeed when you are building out walls to the edge of the map. The game won’t let you do this so that you or a mob cannot walk around the ends of the walls, but you can drop a boulder there to make it impassable.

[ShadowDuelist]

Use them to enclose in a corner of the map next to your base 5 bunny huts and a spider den. Every once and then you can check the place since it will be flooding with silk, spider glands, rot, maybe some carrots, spider hats and spider Eggs.

What happens is that besides the usual fight between bunnymen and spiders, every once and then a spider queen will spawn leaving another nest lvl 1 behind. Since she cant escape the boulders,  she will eventually die to the constant waves of bunnymen, dropping a spider hat and spider eggs, and the cycle will start again over and over.

Use it as an undestroyable "wall" during the full moon event. It really works,and it never disappointed me.

Mine them for rocks.

That's a lot of walking while carrying boulder. I'll just stick with statues and endtables. They work the same, and don't require as much work with transportation.
