Any idea on how to script pose manipulated models?

So I've got this lil easter egg going where this pose manipulated model is sat on a toilet. All I wanna do is delete it from the toilet. I've basically finished the scripting but the pose gets messed up when i make it script_model. when its a misc_model its fine though. any idea how to fix this? I've included images to show what I mean when I say it messes up in game.

That's not the way I want to do it. I know theres a way to make a model scriptable but im not sure how. Also don't own maya and not willing to learn how to use it ¯\_(ツ)_/¯
