Hey there, here's my sound pack for 1.18 Minecraft, which changes the underwater ambience sounds to something """more spooky"""

Replaced ambience files:

Animal1: "Watch yo jet"
Animal2: "Number 15"
Bass_whale1: "time, Dr Freeman"
Bass_whale2: *Bioshock intro*
Crackles1: "LIQUID! SNAKE!"
Crackles2: *Spongebob intro*
Dark1: "Chicken Nugget"
Dark2: "it don't go down"
Dark3: "OBJECTION"
Dark4: "Memes, the DNA of the soul"
Earth_crack: *Springtrap Death*

These sounds have been edited to make them sound more realistic for when underwater.

NOTE: Underwater ambience happens A LOT more frequently then cave ambience, so you might hear sounds overlapping others, just keep that in mind.
