Danger Zone D-15 is the fifteenth level in Danger Zone. The objective of level D-15 is to use the birds to eliminate all the pigs. Get at least 120,000 points for 3 stars.
This level is hard for not having enough birds to use.
Getting 3 stars is not easy.
Send the Lazer Bird just to the side of the top-center tower, then redirecting it through the snow and into the top-right structure. Use Terence to clean up any remaining pigs on the right side. Send the Lazer bird toward the middle of the top-left structure, then redirect it vertically through the snow. As debris cascades, it is possible to pop the bottom-left pig via debris.
