The spiders are your friends and can be found just above the cauldrons. Your points will increase when falling bubbles bounce on the spiders below. The more spiders a falling bubble hits, the more points you get. Spiders will appear when you make several bubble-clearing shots in a row; however, beware! You will lose two spiders for every shot you miss.
Blue spiders
These are basic spiders. You will score a point each time a bubble hits them.
Yellow spiders
Earn double points when the bubbles hit yellow spiders.
Green spiders
These spiders are special and will clone the falling bubble, creating another bubble that will gain you extra points.
