The Big Setup 10-15

Theme 10-15 is a reconstruction of Theme 5-17, and this theme is replaced to 3 Big Brother Birds, 6 Pigs, and all of which has construction hats. You will have an achievement for world 10, the mason moustache. After completing world 10, you will proceed to Theme 11-1. 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.
