Angry Birds Space Cosmic Crystals bonus level F-7 is unlocked by feathering all levels of Cosmic Crystals. The strategy is to toss the first can clockwise, calling for the Space Eagle directly above the TNT. This should clear the west planet and TNT, but leave everything else intact. Go counterclockwise next, calling for the Eagle between the planet and remaining TNT. Again, the last planet should remain intact. Finally, follow the flashing arrow to pop the mustache pig. If you have an alternate strategy please feel free to leave a detailed comment below.
