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. 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 only power up that won't be on Angry Birds Space is Sling Scope. This is because when you pull back the slingshot, it shows you where your bird will be launched.
 * The planet's name is a pun of the Bad Piggies, and the world famous Big Dipper constellation.
