Pig Dipper

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. It was also confirmed that the Power Ups should be coming to Angry Birds Space (while some no-life haters and some minor fans believe this may be false). Currently, there's no actual pictures of the planet, but some fans have made fan-art of it. For more info, check the following link proving its existence.

Trivia

 * The Sling Scope may not be coming to Space (due to the fact you can use its power in any level without the power-ups at all). While it's possible, the new shoot able TNT crates will replace it in the game though.
