Starting Bubbles: 60
+7 bubbles in the Cauldron,
+ 3 holes in the ceiling
the Charm of Disarm
Points needed for 1, 2, 3 Star:
80 000, 100 000, 115 000
1 Bomb Bubble
You do not see the Bomb when the level roles up, so bursting the lowest rows before you go for the Mystery bubbles and above them is a good idea.
Special 3 Star Tips: Use the yellow spider potion as well. Green spiders are not really needed more then in the lower section of the game.
