This is a Style embedding which makes your subject go full goblinmode, literally! Think green skin, horns and long ears! Simply throw Style-Goblinmode on to the end of your prompt (or the start, if the effect doesn't come through strong enough), and bam! - your subject is now a cute goblin - it's as easy as that.

Note that some positive and negative keywords will lessen the greenskin effect - negative token "ugly", or "Bratty" in the positive, for example, will remove the green skin from many models. Experiment and see what works best! Also, some models accept the skin color better than others! Also, also, fair warning, it wants to make your subject naked, and female!
