Green Mist (How To?)

Hey y’all so I was wondering if anyone would be able to point me in the right direction with making a smoke simulation like in this scene:


I’m not good in simulations but first make some smoke… and then animate the smoke source in such a way that it pauses a little after every step… maye some additional wind force… the problem for me would be: making smoke that any other than me could recognize as smoke :wink:
