Use PFlow to create smoke that follows specific shapes?


So I have this character I’m creating that needs to have smoke coming from their body. This is simple, except I also need that smoke to follow or take certain shapes. Like, say, i need it to have the shape of an arm or follow an arm in a way that doesn’t leave much of the arm visible. I need very thick, black smoke to almost mimic a body , essentially. Any way i can achieve this without plugins?
