You have a cluster of black bubbles in the bottom centre and a cluster of mystery bubbles on each side wall with a virus bubble attached to them. Also a chain with two locks with a bomb beside each one.
Start by dropping the black bubbles and clearing the sides before the virus spreads too far down. Next work your way through the locks on both sides being careful of mystery bubbles in case they are bombs. Open the chain and be aware the bombs are now ticking !!
Clear the bombs before they go off and work your way up to the ceiling, getting green spiders before you drop it.
