Ice Block Sheet

Ice is light blue in color and can also be called glass. Among the three kinds of blocks, this one can be easily broken by all kind of birds. Levels with these blocks are often provided with Blue Birds, as they are very good at breaking these blocks. It is suggested to mutiply the bird in front on the ice block to maintain the greatest strength of the bird. Most birds slow down when they hit glass, but Yellow Bird slows down after only breaking one bit of ice.

Tips

• Blue Bird is very helpful on destroying ice, especially when "shotgunning".

Trivia

• Strangely, Yellow Birds are weak against stone, despite stone having a much stronger strength than wood.
• Boomerang Birds and Yellow Birds can destroy ice.
