Utopia 4-25

Utopia 4-25 is the 25th level in Utopia.

Difficulty
It's may be very hard to kill all pigs with Blue Birds. Fortunately, it has some TNT to damage the fortress, but it's still hard.

Strategy
Fire a blue bird towards the top left pig, splitting a little over half way there. The goal is to pop as many kernels as possible and push TNT into the gaps in the stone structures. This requires quite a bit more luck than skill, but keep trying and you’ll get it eventually! You can 1-bird this, but it’s also possible to 3 star using two birds.
