Precision
Part 1.
Clear as much as you can of the right side first without breaking the chain to stop the spread of the shadow bubbles. This will ensure you have enough bubbles to get through Part 1. Clear the left side and THEN break the chain.
Drop the bombs on the left. This usually isn't too difficult. Then drop the skulls in the center. While you're at it, depending upon the bubbles you're getting, clear the right side before breaking the lock on the 2nd chain.
Drop the bombs on the right. Again, this usually isn't too difficult.
Make your way to the ceiling to clear 9 holes to drop it all.
Part 2.
Clear left side first to stop infection. Clear right side and break chain.
Clear right side to stop infection. Drop skulls in center.
Continue clearing right side before breaking chain. When you do, a bomb will be activated on the right above the infection.
Drop the infection immediately using Rainbow bubble if necessary. Drop bomb but do not break chain yet.
Clear left side and then break chain. Two bombs will be activated on ceiling.
Drop center skulls immediately using second rainbow bubble. Now would be a good time to use the bomb charm to stop the two ticking bombs on the ceiling.
Clear ceiling and drop it all.
