This level is very hard because:
- Getting three stars is very hard.
- This level needs luck than many levels in the game.
- Timing is the key to successful.
Target the asteroid north of the level with the Red bird. With a bit of timing needed, send the Lazer bird through the bubbled pig, avoiding the TNT. Doing so will cause the TNT to drop onto the structure below. Finally, snipe the remaining piglet by sending the Red bird clockwise around the planet or directly at him.  Note: First and second shot is extremely challenging.
