Theme 1-3 (aka Smile Hill) is the 3rd level in Angry Birds. It contains two Small Pigs that must be destroyed, who are placed on the other side of a "hill" made of ground. On top of the hill is a smiley block , and to the right of the Small Pigs is a small construction. This level introduces how the player must use the various environments in the level to their advantage.
Three Star Strategy
Fire the first Red Bird into the wooden sphere on top of the hill. It should roll down, squash the pigs, and take out some of the wooden blocks in the construction on the other side. The player should then have three Red Birds left over, for an extra 30,000 points.
