Well I've heard that Roblox is gonna be letting people customize their death sounds (somehow, not sure EXACTLY how it's gonna work), so most people are probably just gonna make it the 'oof' sound again.
All you need Is to swap uuhhh.mp3 to an audio you've downloaded and put the default one somewhere else and the other renamed uuhhh.mp3 in the sound folder. And VOILÀ!
