You need to drop the cluster of 3 Doom Skull Bubbles to the right very fast. Look at the picture to get what we mean! The picture also have a line marked on it, that is the lowest you can let the infection spread. If the infection spreads lower than that, you will not be able to see beyond the left side infection so you can know what color bubbles you need to shoot there.
The second picture shows how it is supposed to be to get the clear sight to the left. When the level rolls up:
Memorize two colors, the one bubble to the left above the infected bubble and the one to the right above the infected bubble. Then you can aim at them in the blind later on and clear all the infected bubbles and the Doom Skull Bubbles by bursting the hidden bubble that you so nicely have in mind, that if you fail to clear the right hand side fast enough.
When you have dropped the infection and the skulls to the left, you will be able to see above the infection to the right!
