Pig Bang 1-5/Space Eagle

Here is the strategy for 100% total destruction with Space Eagle for Pig Bang 1-5 (Angry Birds Space). Note: You must have least one sardine can to play this mode.

Difficulty
The fortress is small, so extremely easy to collect feather.

Strategy
Send the sardine can as one normally would to clear the level, but after the can hits the structure, trigger the Space Eagle when the can settles at the foot of the tower. A majority of the shrubbery on the planet will be destroyed if the wormhole is on the surface.
