You can get all three stars in this level by only using four angry birds.
- Aim the first angry bird at a high angle to take out the pig on the far right. Do NOT knock over the front structure.
- Aim the second angry bird at a low angle to smash straight through the vertical wood blocks on the front structure. This should clear out the front structure as well as getting the pig on the left.
- Aim the third angry bird at the rock floor, just to the left of the pig on the far left. It should break through one block of wood and get one pig, leaving a vertical wooden support beam.
- Aim the fourth angry bird right at the inside corner of the exposed wooden support beam and drop the egg right before the bird hits. This will get you the last pigs. It needs to be done this way to get enough points for three stars.
