This is our walkthrough video for Angry Birds Rio Carnival Upheaval Star Bonus Level #13. The level is unlocked by earning 30 stars in Airfield Chase. Loft a Yellow bird high, blasting the large cage on the left and detonating the TNT between the first two structures. Once the left structure is clear, send another Yellow bird through the foot of the far tower, causing it to topple and crush everything below. The score in the video below is 107,230.

Very good strategy – repeatable. I found it easier to send first bird flat – it destroy the birds, roll and fall on TNT. Second bird the same as on video.
Excellent strategy for first bird, thanks for sharing
Thanks for the tip. It took some doing because that pesky little blue bird on bottom of 2nd structure just wouldn’t die but persistence paid off.
I cannot get second shoot as video, any advise?
The second shot is easier than the first. You can’t destroy the hallow block with yellow?
I stuck on this more that a week.
When i shoot, either destroy both block (will just cut off tower) or hit above blue&red cage.
