Pig Bang 1-30

 Pig Bang 1-30 '''is the 30th and the last level on Pig Bang.

Difficulty
This is the boss fight. This level may be hard to pop the space bubbles to get asteroids.

Stragety
One strategy to defeat the Space King is to wait for him to fill all bubbles, which maxes out around 10. Then send birds through the top-most bubbles, causing a cascade of vegetables and boulders. Note that hitting his buggy with birds, or hitting its roof, does not do significant damage. Instead, you want to hit the wheels and chassis. Disable his buggy using less than three birds should nearly guarantee three stars.

Trivia

 * This is the first level that you don't have to defeat a pig.
 * The Black Bird can damage the vehicle by exploding.
