grunt with yellow glowing eyes?

[Acies]

It might be done with either billboards or particles :>

View --> Outline bind them to the bone in the head.

If billboard --> Connect those to a pointlight with zero radius. The pointlight works as an "activator".
Then deactivate the grunt through scripting (I don't remember scripts):
Setentity "grunt" false
FadePointLightTo ("grunt_1_pointlight_1", 0,0,0,0) --> Sets billboards invisible
