don't worry, it's not cheating. It's a simple character settings bug.
I think i have seen this when you take the code from a charcter that's slimed and pasted it to a non slimed character.
One of the reasons I love the slimed character model.
I'v never seen this before how is it done may I ask? I tired to do similar but couldn't get the ribcage look at all I know it has something to do with the code for the character but that's it
it's easy to do. You need the old version of this game and you need to experiment there
