Power Activation Point
Activate your power shortly after you hit the big ice block.
First Shot Result
The ice and metal blocks get pushed to the right, and triggering the bomb. This shot should take out all of the pigs except for the bottom three. Note that you can sometimes take out more pigs. But usually you will need your second shot to pick up the survivors.
Aim for the bottom wooden and metal blocks.
Second Power Activation Point
Tap for the jedi power before you hit the blocks. You want to send as many blocks flying as possible.
Second Shot Result
The flying blocks kill all the bat pigs and trigger the TNT. Once all the pigs are dead you will have enough score for the three star rating.
