Electric Candy Bomb

You will need to send us a screenshot, or at least let us know which level you are talking about. We can't tell what it is you are talking about otherwise.

Thanks for the screenshot. I don't think this is a different booster, it's probably just a colour bomb with weird graphics. I think I've seen this in my game once or twice, a colour bomb exploding with sparks coming from it. I'm not sure what it means, I'm afraid.
