Danger Above level 8-15 is the spot where the Golden Egg #13 is found. Since the egg is placed beneath the slingshot platform you should use either the boomerang birds or bounce the yellow birds against the bouncer on the right. Once in the golden egg level itself, try to shoot the red bird in a way that wipes the balloons that hold the pigs.
Below you will find the video that shows both the location (or how to find it) and the starred golden egg level walkthrough itself.
