Season's Greedings

Season's Greedings is the second holiday-themed episode of Angry Birds, released as part of Angry Birds Seasons. Users who downloaded the separate Halloween levels released earlier were given the Season's Greedings levels as a free upgrade.

Season's Greedings is unique in that it contains 25 levels, which open one per day, advent calendar style. Because of this format, the player can't unlock additional levels by completing them in order like in other episodes. Thus, the levels can be tackled in any order the player desires, proving that the required levels were passed. To open the levels, the player must have a wireless internet connection. By default, the level is locked, and if the player attempts to access it when not connected to the internet, he/she'll be presented with an error message. But should the player connect successfully to the Internet before opening the levels, they'll load the level and will never encounter the problem again. Rovio has stated that an update would be released following Christmas Day 2010, when the twenty fifth and final level was released, which would open all of Season's Greeding's levels, but even after the Valentines' Day update was released in February 2011, error messages can still be received.

The PSP Minis update will land on December 1, 2009.
