It is impossible to implant new monsters after 9.4
If you are using an older version you can only create duplicates & reskin them or with blender moddifier but you have to use the default annimations & motion code after 9.4 because from 9.5 onwards everything is integrated in the sframe so it's impossible to create anything at all ....
