Danger Zone D-3 is the third level in Danger Zone. The objective of level D-3 is to use the birds to eliminate all the pigs. Get at least 104,000 points for 3 stars.
Three pigs in the single bubble in atmosphere is tricky.
Send Terence into the top structure, pushing debris onto the TNT so to pop the suited pigs outside the atmosphere. Send the Blue birds around the planet, basically like an extraterrestrial water slide. As they approach the pigs at the bottom, split them. The TNT should detonate via debris.
