Template:Theme InfoboxDanger Zone D-23 is the twenty-third level in Danger Zone. The objective of level D-23 is to use the birds to eliminate all the pigs. Get at least 110,000 points for 3 stars.
The iron blocks is very annoying.
The fortress is complex so it's hard to complete. Fortunately there are many TNTs in this level.
This level is based on luck.
Send the Ice Bird straight ahead into the wire block, detonating the TNT via freezing. (This first shot is extremely challenging.) Send the Blue Bird under the bottom planet, splitting while still in its gravitational field so that some birds detonate the TNT on the right planet. Send the Lazer Bird along a similar trajectory to finish the level.
