Danger Above

Danger Above is the third chapter in the handheld game of Angry Birds. It consists of three worlds, 6 7 and 8.

The pigs are attempting to fly into space  WITH  the eggs. The only achievements are Hovering Helmet, Mounting Moustache, Green Baron, Episode 3 - Total Destruction and Episode 3 - Score Addict.

So, the Green Bird first appears in this episode, first seen in 6-4 locked in a cage. Once the level is completed, you will unlock the Return to Sender achievement.

Plus, World 8 is like that of Season's Greedings and like The Big Setup, the last level (8-15) has a Golden Eggs.
