The Big Setup 10-15

 is the last level of the second theme in The Big Setup. This level is easy to complete but it has a very high challenging to get 3 stars.

Strategy
If you want to get 3 stars, it relies entirely on the first shot. Launch Big Brother into the arm of the crane, causing the TNT to fall. The lower the TNT falls before detonating, the more likely to trigger a chain reaction. If all of the pigs are not popped yet, clear the remaning structures the second Big Brother.

Trivia

 * This level is a reconstruction of Theme 5-17.
 * Some people think this theme is easier than Theme 5-17 (the level the pigs are trying to re-create) because the Big Brother Birds are stronger than the original birds.
 * You can only get 3 stars when you clear the level with 1 bird. That's why it's very challenging.
