Shadow bubbles spread to all normal bubbles, one bubble in any direction for every time you shoot a bubble from the cauldron. You can use this knowledge at some levels as a part of tricky strategies.
As an example you can think on level 167. At level 167 you actually learn to LOVE Spider bubbles. That is because the Shadow bubbles don’t spread to them. At some levels you can successfully stop virus bubbles by letting shadow bubbles spread under the infection.
When you hit a Shadow Bubble with a matching bubble from the Cauldron, it steals bubbles from your Cauldron. This is an awesome way to earn lots of points, if you do the timing correct. Bursting shadow bubbles when you have green spiders can be quite lucrative!
