Yeah, even I have noticed the same. Once while playing level 26 I was at such a position that I was getting certain unwanted bubbles in my gun to shoot. It was the pink standard bubble. In the game there was no requirement of this pink bubble as all the bubbles of this color were already vanished. So I shot the first pink bubble at the extreme left side as there was some empty space. Now at the opposite right corner side there were about 3 to 4 bee hives so you can take it as one of the reason why I shot the bubble at the left side. But interestingly donít know for what reason I found that some huge number of bees came down and started attacking me. However ultimately I dropped my strategy and simply played a normal game.
