Pig Dipper

Pig Dipper is the 6th episode of Angry Birds Space. On Angry Birds Nest, Wednesday December 5th, 2012, a new episode for Angry Birds Space was leaked as "Water Galaxy", but was apparently changed to Pig Dipper. It is somewhat similar to Piglantis, due to presumably having a new water/liquid element and theme. The Power Ups were also introduced in Angry Birds Space.

Trivia

 * The only power up that isn't on Angry Birds Space is Sling Scope. This is because when the player pulls back the slingshot, it shows where the bird will be land.
 * The planet's name is a pun of the Bad Piggies and the world famous Big Dipper constellation.
 * While in water, the Ice Bird creates an ice meteor while showing its icy explosion.
 * Fiery meteorites which were in Red Planet are included in some of the levels. When they go underwater, they cool off and the water puts out the magma around them, becoming inactive.
 * This is the first update of the Angry Birds games in 2013.
 * Some of the "planets" appear to be actual living giant fish. Some of them are larger, and have sharp teeth and are asleep.
 * This is the third time King Pig appears as a boss, and the first time he returns in the game after Cold Cuts.
 * Some birds react differently to water physics; light birds like the Lazer Bird and Lightning Birds will float on the water, while bigger ones like Terence and Bomb will sink.
 * Oddly, the pigs can survive underwater forever. They look like they are holding their breaths.
 * Light weight birds' corpse sprites appear automatically when they go in and out the few times in water.
 * In the sound files for Angry Birds Space it is refered as "water galaxy".
