They are harder than purple, pink, yellow and blue disguised spiders.
Their shields are hard to break because they are made out of bedrock and bricks.
Green disguised spiders are only in compasite levels. You do NOT want to
be around these creatures, they are so evil. There are 6 of these for the
boss in the 16th level. Try attacking these creatures from behind and they will
not know that you are behind them and thay are dead. Use your laser gun
to blast their shields and the shields will break into little pieces.
