Angry Birds Update of December 2012

Angry Birds has recently had an update. It's time for pink bird to join the party! Pink bird( who was first in angry birds seasons) has come in the second set of birday party levels. Pink bird makes bubbles that lift things in the sky and when they pop they drop them. The birds in this set of levels also have birthday hats! Also there is another set of Bad piggies levels so be sure to update.
