Utopia 4-4

Utopia 4-4 is the fourth level of Utopia.

Difficulty
It's extremely hard to cear all pigs with one bird that is the key to 3 stars.

Strategy
Send the Blue bird toward the top-left bumper, splitting relatively close to it. The goal is to clear at least the left and top structures via the TNT and popcorn kernels. With a little luck, you can reach the kernels near the right structure with debris, but use the Lazer bird otherwise.
