Golden Eggsteroid 7 is located on level 4-16 of Angry Birds Space. The Golden Eggsteroid is hidden in the bushes directly underneath the slingshot. Burn the Blue Bird, then fire the Lazer Bird backwards to get it. Once you hit the egg, you’ll immediately be transported via a wormhole to the level.
King Pigs are tricky for some.
One strategy for 3-starring this level is to fire the Red Bird at the bottom TNT while popping the top pig closest to the slingshot in the process. If needed, fling the next Red Bird around the top hitting the lollipops while taking out the bottom pig so the tower of pigs smashes into the planet.
