This will replace the sound files for mobs such as lions, tigers, (not bears, sorry), lynxes, and feral druids. All sounds they make will be replaced by Markiplier making sounds as heard in his MEOW video.
To install: This is a collection of sound files that goes directly into the Sound folder in your World of Warcraft folder - not in your addons folder! Extract the folders from the zip, then move the folders "creature" and "SPELLS" into World of Warcraft > Sounds. - - Note: If you have pre-existing files in that folder, make sure you do not replace what is there already!
(All rights to Markiplier's material go to him. I do not own these sounds or any of the source material. They're his voice after all!)
