As if normal cave sounds weren't already spooky enough, especially with the addition of four more in 1.21, what if we made them even worse?
This pack replaces the ambient cave sounds with the whispering sfx of The One Who Watches mod by Pixel_Coder in order to grant some aspect of horror in vanilla. It's the same concept as my other pack which does the same thing but for the Cave Dweller sounds by Gargin. Sounds are only volume adjusted slightly. Credits file included in the pack.
Subtitles are removed for cave sounds, although you won't hear anything 30% of the time by design. They also play in the Nether. Have fun! :)
