Collect 130 stars to unlock the Rainbow Bubble. The rainbow bubble is purchased by 2000 in-game coins as a Magic Potion. You can use a rainbow bubble twice per play ground.
It will match any ordinary bubble and burst every ordinary bubble it comes in contact with.
You can use it twice / game and when purchased it is active for 3 games.
If you have 10 spiders and at least one is a blue spider, you can shoot a rainbow bubble at a virus bubble, black bubble, in the ceiling or at a Spider bubble to get a green Spider!
If you hit a single Spider Bubble with the RB Bubble, the Spider Bubble usually doesn’t spits Potion.
Greetings from Shelea:
if you use the rainbow bubble to hit the ‘crotch’ of two different colored bubbles, you get rainbow credit for both colors
