Golden King Pig

The Golden King Pig Level is located in the Golden Eggs section and is only available for iOS, Android and Blackberry Playbook's QNX. It's also available for the free version. To unlock it, you must get three stars on all levels. There are many features that include King Pig, Material Mix-Up, Bird Frenzy, and Total Destruction. At first, it was available exclusively to iPad, but on October 9th, 2012, the Golden King Pig Level had been updated for iPod Touch and iPhone apps and Android Apps via Google Play and PC.

Bad Piggies' Powers

 * Normal Pig: No ability, but makes a battle cry: "Nyaaaaah!" (Takes the role for Red, the Red Bird)
 * Small Pigs: Splits into three (Takes the role for the Blue Bird Trio: Blue Jay, Blue Jake, and Blue Jim; AKA: The Blues)
 * Jetpack Pig: Speeds up (Takes the Role for Chuck, the Yellow Bird)
 * Bomb Helmet Pig: Explodes (Takes the role for Bomb, the Black Bird)
 * Bowling Ball Pig: Drops an exploding bowling ball (Takes the role for Matilda, the White Bird)
 * Beaked Pig: Boomerangs back (Takes the role for Al, the Boomerang Bird)
 * Fat Pig: Has the same pitched battle cry as the Normal Pig, but has stronger stength to destroy most obstacles, even stone (Takes the role for Terence, the Big Brother Bird)
 * Balloon Pig: Inflates (Takes the role for Bubbles, the Orange Bird)
 * It's possible that if Stella, the Pink Bird, will be updated in Angry Birds Classic, maybe a new pig might take her role and ability in King Pig Mode.

King Pig
In "King Pig", the birds turn into pigs and the pigs turn into eggs. You have to complete the level by destroying the eggs with your available pigs in the slingshot. The different ways that the pigs use to solve their problems with the unique abilities is humorous, two of them are even lucky to have a splitting ability like the Blues and a ballooning ability like the Orange Bird- the balloon pig even looks like a balloon. And who to simulate Terence than the Fat Pig from Angry Birds Space? The Bad Piggies are playable in this mode, and yes, they are STILL BAD as the enemies (pigs) are replaced with eggs, which could possibly mean the Birds had decided to take the Bad Piggies' role by building forts to protect eggs. The pig with an exploding bowling ball resembles and takes the role for the White Bird, by dropping the bowling ball (or should I say "bowling bomb") on the fort protecting the eggs. The Pig with a jetpack speeds up like the Yellow Bird. The Pig with a helmet contains a fuse on the helmet, enabling the Pig to explode like Bomb Bird. The Pig with a long, fake beak boomerangs back like the Green Boomerang Bird. Likewise, who could never forget to replace Red's role than with a normal Minion Pig?

Material Mix-Up!
In "Material Mix-Up!", the game will switch some materials in the game for example: The materials in the level are glass, wood, and stone. The stone will either turn into glass or wood and the glass or wood will turn into stone, thus it is either easier pickings for the player or a lot harder.

Bird Frenzy!
In "Bird Frenzy!", you will have unlimited birds and you have to complete the level in the amount of time it gives you. Normally the time limit in Bird Frenzy is between 30 seconds for most levels, 40 for some, 50 for others and 60 for a few lucky ones.

Total Destruction!
In "Total Destruction!", you have to complete the level by tapping it to cause small explosions and you only have a limited amount of time to do so. Usually the time limit is 10 seconds.

Trivia

 * All the Pigs make the same launch noises, tap noises (battle cry, even when using a pig with an ability), and pain noises. Plus, in the King Pig mode, their victory sounds are the same sounds you normally hear when you fail a level. If you lose a level in the King Pig mode, you just hear a pig snort (The same one from the cutscenes).
 * If you complete a level, the King Pig cries in the minigames "Material Mix Up", "Bird Frenzy", and "Total Destruction", while the King Pig laughs in the minigame "King Pig". The opposite happens if you fail a level.
 * It is unknown how the Fat Pig got from space to the Angry Birds world. However, the Fat Pig in Angry Birds Space has a different spot pattern from the King Pig Mode Fat Pig, so this Fat Pig may be the Space Fat Pig's Earth counterpart.
