I think this should go into suggestions, Because I don't beleive there is a way to do this, there is a different sound effects the pc toribash uses.
Enable sounds turn up volume etc and you will hear it is very similar to the wii sound effects.
Download the sounds from here: https://cache.toribash.com/movies/
Then go to your toribash directory -> data -> sounds, then replace what you want to change.
p.s. don't c/p the whole sounds folder, it wont fit great
