Pic EI 57-5: You are 1 row from being able to see the ceiling.
Unlock your chain on the left side. You will be wasting some bubbles due to breaking the Crystals. Move from left to right unlocking the 4 chains. After unlocking the second chain you will notice a morph under the Lock. You can remove that before unlocking the next chain and not have to worry about it spreading upwards. After the last chain is unlocked you will notice you have 2 Bombs ignited and 3 infections coming down from the ceiling. Concentrate on either dropping the Bombs or plugging them up. Once you have the Bombs under control, move towards the ceiling and drop it. TIP: Save your Rainbow bubbles for extra help with the Bombs.
