Transplanting a butt onto yourself should change your fart

[UrsulaMejor]

Specifically, to the fart sound of the original owner, which i believe is pitched differently depending on the age you set.

You should also not be able to fart properly if you have no butt. like a hissing noise. or a sad slight fart.

i remember when if you pooed too much, you'd eventually just shoot out gibs and then die/explode due to your butt falling off

it'd be hilarious if this happened again
