Can anyone please help me convert this MMD model into a ragdoll for GMOD?

I would like to convert this MMD model into a ragdoll for Garry’s mod, but I don’t know how to do so. Can somebody please help me out here? The model is right here: http://download855.mediafire.com/z84nq28440sg/t02mgyznmdx/Keroro+Gunsou.pmd
If anyone can help me out at all, that would be great

What the actual fuck.
