So, this project started as one to change the Spider's sound effects (which I'm leaving in), but turns out that some enemies also use those very same sound effect files. So uh... The enemy now makes squeaky footsteps when walking around (The Bracken gave me one hell of a laugh)
Known Enemies with Squeaky Footsteps:
Spider
Bracken
Sporedog
Should work out of the box if downloaded using the Thunderstore.
I don't believe all players need this mod to prevent desyncs but never know.
