On the basis of the video Helen's stomach is doing most of the flashing - is it so, or does the video give a wrong impression?
Her stomach, or the lava around her stomach actually, is where the color changers are so it really depends how you set it up as to how much it looks like its doing. The color changers have controls you can set how you want. But they do go all the time, there are flashers around most of the rest of the backbox but they go with the game so they wouldn't be flashing in attract mode, maybe that's what you're seeing in the video.
