3 Bomb Bubbles
Clear along the bottom, avoiding the bombs so the screen drops. Next clear up the side being careful of the shadow and bomb on the right hand side. Once the side is clearer, go across the middle and before you drop the lower black bubbles collect green spiders. When the lower bubbles are dropped, you should see the ceiling.
Clear the left side and up to the ceiling, avoiding the remaining shadow and bomb as much as possible. If you cannot see the ceiling clear the left as much as possible before taking some of the shadow from the right, this is because the bomb will be activated. Try again to get green spiders before you drop the ceiling.
