editing monsters?

[WALP]

My main goal is that I wanted to put a mustache on one of the grunts and a statue. I have no idea how I would do that though.. help?

The statue would probably be the easiest to do, as you would just have to attach the mustache model to the same body as the helmet(in the model editor).

The grunt is not as easy though as it is animated and im not really the guy who has a lot of knowledge on this but expect to be fiddling with maya and stuff.
