You just need to get to and hit either of the lightning bubbles. To do that, you need to first flip three different light switches, and they have to be done in order: middle, right, left. You need to do this as quickly as possible, so be sure to hit the middle switch with your first bubble. While you are waiting for the right color to come up in your queue to go after the right-side switch, attack the ice bubbles above by clustering different colors together in different parts. There are only three different colors of bubble in play at the start, so cluster the three different colors in three different places: off to the left above, off to the right above, and straight above. This will enable you to start coloring and popping ice bubbles, which you will need to do to clear the way to one of the lightning bubbles. On each turn, look for the best available shot to either pop as much as you can, or to clear the way to switches once the color of bubble you need to do that is available. Give priority to the latter.
