The timing of when you use your splitting power is important to get the three star for the stage. Launch with a wide angle into the wind blower. Consult the picture if you want to know the exact angle.
Power Activation Point
Activate the power after you have been blown and heading up. Tap the split power before you bump into anything.
First Shot Result
Your split will break the ice holding up the chain. The wind blower then sets loose which blow everything including the bomb. The chain reaction kills all the pigs and leave you with the cool three star rating master.
