Bubble Witch 2 Saga has a special gameplay mode once you've passed Level 26, on the mobile apps only.
It is called Magic School.
In Magic School you'll be able to brew special potions to help you in the game.
Each potion requires a specific number and color of bubbles that can be collected as you play.
Then you wait the allotted time before you can use them.
