Starting Bubbles: 40
Recommended Potions: Rainbow Bubble AND +3 holes in the ceiling
Points needed for 1, 2, 3 Star: 75 000, 110, 145 000
9 Bomb Bubbles
The rainbow bubble is good if you can’t take out some row to get to see the ceiling fast enough. You can stop the bombs in the ceiling by shooting bubbles under them, if needed. If you shoot down the ceiling with the Upper Bombs unstopped, the level is worth only two stars.
Here is a 3 star video (no Chams) to guide you.
