Use yellow to ignite the TNT in the wood block.
If anything remains,fling green backwards and then click immediately after firing.This should hit the pig inside the wood block hanging in the rope and TNT.
If it left 2 pigs,then use green bird to kill them(It is your choice,you can fire green backward,forward,at a high angle or without clicking it.
My score is 81800.
