Fire Extinguisher 1.2 - 'Bad Motivator'

With most of R5 pieced back together, i've been starting to plan the extras that I want to fit into him. Now I have my Radio Controller unit, and have been re-reading forum posts on extra switch controllers, the simple 'Fire Extinguisher' project, just stepped up a notch lol.

I'd like to link a sound effect of R5's motivator blowing with the Bad Motivator popping up and 'mist' effect coming not just out the pie hole at the top, but also from around the edges of the dome, as seen in this screen grab from behind the scenes vintage footage.

Not sure I can manage the flash as well......but you never know.....
I have sketched up an idea of how it might look, but of course it has to be tried and tested.
