Cosmic Crystals 7-30

Cosmic Crystals 7-30 is the 30th level in Cosmic Crystals. To pass thus level, you must kill the Alien Pig boss. Get 34,000 points for three stars.

Difficulty
It's extremely hard to feed the asteroids to boss. And this level is very hard to get three stars.

Strategy 1
Lightly nudge the asteroid in the southwest of the level, having it settle in the wormhole nearby. The rotating boss spaceship will eventually pull it in on itself. Try to do the same with the Blue birds and the next asteroid. Use the Lazer bird to detonate the TNT on the crystal planet, sending more asteroids in the path of the boss’ ship. If you have hit the boss twice, send the Black bird straight ahead for the kill shot!

Strategy 2
Send Red Bird to knock the southern asteroid that is connected to the crystal planet to the black hole. Wait for the Alien Pig pulled it. Lightly nudge the asteroid in the southwest of the level by Blue Bird, having it settle in the wormhole nearby. Send the Lazer bird to detonate the TNT on the crystal planet, sending more asteroids in the path of the boss’ ship. (Note: You can switch the first two shots.)

Strategy 3
Send Red Bird to knock the southern asteroid that is connected to the crystal planet to the black hole. Wait for the Alien Pig pulled it. Wait for the crystal planet comes from the pig. Send the Blue Bird through the atmosphere of the appeared crystal planet and knock the pig's module of the ship. Send the next Lazer Bird and redirect to the pig's module to finish the level.
