South Hamerica 1-22

 is the twenty-second level of South Hamerica.

Strategy
Sling Blue Bird through the waterfall's glass block to destroy all of the TNT boxes and smash the boat which is having the eggs. Then sling Matilda and drop the egg bomb next to the left of the backpack which is at the right and next to the left of a Medium Pig. Then, she should bounce to the left of the screen and rolls back to the river (the ground which is having triangle glass blocks) for bonus icebreaking points and to smash Foreman Pig. Then sling Stella and pick up the Small Pig which is in a square wooden block in her bubbles. Then, when the bubbles popped, all of the blocks that have trapped will fall down and smash all of the pigs below. This and the three remaining birds will give you a total of 170k+ points.
